I never really thought I would become a mathematician. Although I enjoyed solving maths problems in my early years of high school, my first love was dance. I wanted to become a dancer. I finished high school when I was 14 years old. At that moment, while deciding what to study in college, a scholarship opportunity for Mathematics came up, and I thought, ‘Why not?’. That ‘why not’ has turned into a career of almost 18 years.

My passion for mathematics truly awakened with mathematical analysis. For me, the concept of approximation is one of the most refined in mathematics. Currently, I am continuing on the path that my undergraduate and graduate advisors helped shape for me. Staying on this professional path is thanks to them and the spark they ignited in me, which makes me want to keep learning every day, as learning is one of the things I enjoy the most.

Although I may have never told her, [my PhD advisor] has always been my role model in this field. My aspiration is to be a source of inspiration and guidance for my students, just as she was for me.

This career has given me the chance to visit unimaginable places, immerse myself in diverse cultures, and have unforgettable experiences. I’ve pushed myself beyond my comfort zone, tackling challenges I once believed were insurmountable, and somehow, I have succeeded each time. Along this journey, I have met incredible, inspiring, and talented individuals who have contributed to my growth both professionally and personally. Resilience and tenacity are two qualities that develop over time in this job.

I was fortunate to have an exceptional PhD advisor—an intelligent, inspiring, strong, and determined woman. Although I may have never told her, she has always been my role model in this field. My aspiration is to be a source of inspiration and guidance for my students, just as she was for me.

Being a mom has put me in the same boat as many others, trying to stay on top of my maths game while being fully present for my kids.

In recent years, my academic perspective has evolved. I wish to remain active in research, but more than teaching, I want to share my passion. My passion is mathematics—its structure, its theorems, and ultimately, its beauty. I believe that by sharing this passion, I can inspire others to appreciate the elegance and depth of mathematics. I aim to create an engaging and stimulating learning environment where students can explore, question, and develop a profound understanding of mathematical concepts. My goal is to ignite their curiosity and foster a lifelong love for the subject, just as my mentors did for me.

One of the most challenging aspects throughout these years has been balancing my professional and personal life. Being a mom has put me in the same boat as many others, trying to stay on top of my maths game while being fully present for my kids. However, being a mother to a child with special needs has illuminated for me the profound societal needs. Specifically, it’s shown me how we need a kinder, more inclusive academic world, one that’s less about labels and more about understanding and support.

Born in Accra, Ghana • Birth year 2004 • Studies physics with computer science at the University of Ghana • Lives in Accra, Ghana • Occupation Level 300 student, financial secretary of department, Huawei campus ambassador for the University of Ghana Huawei ICT Academy

I have always admired Marie Curie, not just for her pioneering work in science but for her fearless approach to understanding the world. Her words “Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.” resonate deeply with me. I look at her pictures and see a fearless woman, reminding me of my journey and the questions I have asked myself and continue to ask: “Can I do this? Am I in the right field?”

My answers date back to my primary school days when my love for mathematics ignited my passion for physics. Even as a child, I was always very curious, constantly asking the WHYS, HOWS, and WHATS. My incessant questions often tired my teachers. I always found simpler and alternative ways to solve my math problems in class, feeling a deep sense of satisfaction when I arrived at the same answers as everyone else, but through a different approach. I’m not gonna lie, it made me feel like a genius.

Physics, as they say, is math in motion.

My journey into the world of physics began with a mixture of uncertainty, optimism, and determination. The uncertainty in my journey into physics arose from many questions about my future profession. In Ghana, physics graduates often become teachers or lecturers, a cycle I clearly want to break. This uncertainty fueled my optimism and determination, pushing me to explore diverse opportunities within the field. Moreover, the complexity and depth of physics as a subject can be intimidating. In senior high school, I found myself facing challenging material that often left me questioning my capabilities.

Physics, as they say, is math in motion. It is one abstract field. Its abstract concepts, such as quantum phenomena, special relativity, classical mechanics, cosmology, and mechanics, captivated and piqued my interest. I was also attracted to how difficult it seemed to grasp these concepts back in senior high school, which made me so competitive. It was either me conquering the physics subject or it totally conquering me.

Participating in The Girls in Mathematical Sciences program was transformative.

I remember being the first female in my school to contest in the national science and math quiz. My specialties as a candidate were my very brilliant skills and knowledge in physics and math. I was basically their human calculator as well as their math expert. I was glad when I chanced upon The Girls in Mathematical Sciences program organized by the African Institute for Mathematical Sciences. At first, I was skeptical about applying because I thought it was a program only for those interested in pursuing careers in mathematics, but my math teacher encouraged me to apply. I did, and voila, I got in. I am glad to have been part of the first cohort. Participating in The Girls in Mathematical Sciences program was transformative. I met exceptional young ladies whose enthusiasm encouraged me to study harder. Their confidence made me brave, and I deepened my passion for physics while learning about diverse career paths. Dr. Angela Tabiri inspired me as well.

I then realized that the program wasn’t geared only towards girls who wanted to pursue math; I met and appreciated the love of my life, PHYSICS. Funny, right? The world has its ways of doing things. I was enlightened on the various paths and careers that math and physics could lead to. At that point, I was wowed. I knew from then that pursuing a degree in physics wouldn’t be a bad idea either. Who knows? I might just be the next female Einstein.

Currently, I have a strong interest in quantum physics as well as machine learning, but I’m still exploring more options and hoping to intertwine physics with computer science.

I discovered various career paths through the program, including quantum physics, aerospace engineering, and data analysis. Currently, I have a strong interest in quantum physics as well as machine learning, but I’m still exploring more options and hoping to intertwine physics with computer science. Before my passion for physics, initially, my aspirations were firmly set on becoming a medical doctor, a path that seemed more defined and familiar (which is every science student’s dream).

My journey hasn’t been without challenges. Being a female in a predominantly male field can be daunting, especially since there aren’t many females pursuing physics. In my class, males make up about 85%. This disparity has been challenging, but it has also motivated me. In the future, I hope to contribute to the field of physics through research and innovation. I want to inspire other young girls, especially those from Africa, to pursue their passions in STEM fields. Curiosity has been my driving force, and I intend to keep it that way.

So here I am, Dorcas Seshie Afi Mawutor, a young woman from Accra with big dreams and a relentless spirit. My story is just beginning, and I am excited to see where this path will lead. Whether it’s unraveling the mysteries of the universe or inspiring the next generation of female scientists, I am ready for the journey ahead.

Anastasia Molchanova

Born in Siberia, Russia • Birth year 1989 • Studied Mathematics at Novosibirsk State University in Novosibirsk, Russia • Highest Degree PhD (Candidate of Science) in Mathematics • Lives in Vienna, Austria • Occupation REWIRE Research Fellow (Postdoc) at the University of Vienna

My path in mathematics was both easy and challenging at the same time. Coming from the distant town of Oljokminsk in Yakutia (it is a north-eastern part of Siberia), with a population of less than 10,000 and no neighboring cities within a 500 km radius, I was fortunate to have a supportive family, teachers, and colleagues who guided me along the way.

(…) An unexpected phone call brought a life-changing invitation — an opportunity to attend a summer school 600 km away from my home (…)

My love story with mathematics began in primary school when a wise teacher recognized my hidden potential and offered me additional classes designed for the brightest students, even though I was not among them. Then, during middle school, my math teacher encouraged me and other talented students to participate in numerous math competitions, where we submitted our solutions by post. Thanks to this, at the age of twelve, an unexpected phone call brought a life-changing invitation — an opportunity to attend a summer school 600 km away from my home in the regional center, Yakutsk. The journey from Oljokminsk to Yakutsk is usually far from being easy. You need a plane ride, a 12-hour ship journey in the summer, or a more than 12-hour car ride during winter (once such a winter trip took me three days due to harsh weather conditions!). Nonetheless, my parents didn’t hesitate for an instant and supported me wholeheartedly.

(…) Mathematics was never a subject that came effortlessly to me; it constantly pushed me beyond my comfort zone

Arriving at the summer school, reality fell short of my grand expectations. I discovered that I was not the top student among my peers, and my vulnerabilities as a teenager made me an easy target for bullies. However, amidst these trials, a remarkable teacher from St. Petersburg entered my life, seeing a glimmer of potential within me. And so, I got invited to join another summer school in St. Petersburg. At that moment, my obsession with mathematics was ignited, and I knew without a doubt that I wanted to pursue a math program at the university.

In my research field, Applied Analysis and Modelling, I have been fortunate to collaborate with passionate individuals who foster a culture of friendship and support. And this unwavering support continues to inspire me, though I encountered numerous obstacles throughout my academic journey. Indeed, mathematics was never a subject that came effortlessly to me; it constantly pushed me beyond my comfort zone. While I excelled in my university studies, the research realm presented its own challenges during my PhD and postdoc. Thus, I have to admit that I often made “easy choices” to maintain a straightforward career path, which makes me sometimes wonder if I was truly choosing mathematics or was simply afraid of change.

(…) I believe that with our collective efforts, we can inspire a generation of aspiring mathematicians, cultivating a system that celebrates the brilliance and potential in every individual

Reflecting on my experiences, I have realized that my struggles lay not only within myself but also within the academic system. The unrelenting pressure to prove one’s worth affects your mental well-being. Receiving numerous rejections makes you question your abilities and leaves you feeling inadequate. Moreover, the “bottleneck” effect in academia — a surplus of opportunities for pursuing PhD and postdoc positions but limited permanent positions available — creates an atmosphere of uncertainty and instability in your life. And my hope here is that we, people in academia, can unite and strive for positive change to cultivate an academic environment that nurtures creativity, inclusivity, and fulfillment.

My journey through mathematics has taught me invaluable lessons in resilience, perseverance, and the power of a strong support network. I can proudly say that each challenge of my path has shaped me into the person and mathematician I am today. I maintain an unwavering optimism about the future of academia. And I believe that with our collective efforts, we can inspire a generation of aspiring mathematicians, cultivating a system that celebrates the brilliance and potential in every individual.

Kira Wetzel

Born in South Korea • Studied Data Management/Information Systems (Master of Science), Education (Master of Arts), and Behavioral Science (Bachelor of Arts) at three different universities in the United States. • Highest Degree Master of Science • Lives in San Jose, CA USA • Occupation Data and Analytics Management and Lecturer at UC Berkeley

Chapter 1: A Love for Math

I have always been fascinated by numbers. From the moment I learned how to count, I was hooked. Math quickly became my favorite subject in elementary school, and I eagerly awaited the Math Minutes exercise every day. There was something thrilling about solving equations, finding patterns, and unlocking the secrets hidden within the numbers, and quickly.

As I progressed through school, my passion for math only grew. I found solace in the logic and structure it provided. While other kids dreaded math class, I relished the opportunity to dive into complex problems and unravel their mysteries. My brain seemed to have a natural affinity for the subject, and I loved the feeling of accomplishment when I arrived at the right answer.

When it came time to choose a major in college, however, I made a somewhat unexpected decision. Instead of studying pure mathematics, I opted for math education. I wanted to make math more accessible and easier to understand for others. I believed that by becoming a math teacher, I could help students overcome their fears and discover the beauty of numbers, just as I had.

Chapter 2: Thinking in Algebra

Teaching high school math was both challenging and rewarding. I loved seeing the light bulbs go off in my students’ minds when they finally grasped a difficult concept. However, as an introvert, the constant demand for live interaction every day was beginning to take its toll. I realized that if I continued down that path, I would eventually burn out.

After a few years of teaching, I decided to make a transition into data management. It allowed me to utilize my analytical skills in a different way while still working with numbers. What surprised me was how well my brain adapted to this new role. I found that my problem-solving abilities translated seamlessly into the world of data.

As I analyzed and processed information, it felt like I was working through an algebra problem. I approached each task as a system of inputs and outputs, seeking patterns and connections. This way of thinking became an incredible framework for tackling unknowns and finding innovative solutions. My love for math had given me a unique perspective that served me well in my new field.

Chapter 3: A New Direction

To further solidify my expertise in data management, I decided to pursue a master’s degree in information management and analytics. The additional knowledge and skills I gained opened up new opportunities for me. I had no regrets about my career path. In fact, my background in math education turned out to be an asset in influencing and teaching at work.

The scariest thing about transitioning was actually the change in working environments. Office environments are incredibly different than classrooms and the dynamics between people are different. There is no option to go to your classroom and hide. The agendas and goals are different. In the office, highly cross functional teams of people are responsible for the success of the project.

Currently, I lead a team of analytics engineers, analysts, and industry strategists. Our main focus is developing data foundations and curating information that aligns with our company’s business strategies. Alongside this responsibility, I am also dedicated to developing leaders within my team. I firmly believe that investing in others and fostering their growth is crucial for long-term success. I’ve learned that this isn’t always the case for others, but it will be for me.

Chapter 4: Battling Gender Bias

Throughout my career, I have encountered the harsh reality of gender bias. It is pervasive, and the intersections of gender further compound the disadvantages faced by marginalized individuals. Closing the gap requires us to be intentional in our efforts. We must take our seat at the table while saving a seat for others. It means having the difficult conversations and addressing the unspoken career setbacks that are often less concrete but nonetheless hinder progress. 

I have experienced oppression and setbacks, even from other women, in the workplace. It has been disheartening, but I have used these experiences as lessons to shape my behavior and align myself with my North Star. If we cannot support one another, how can we possibly advance as a collective? I have made a conscious choice to accept slower advancement if it means providing greater opportunities to others. My decisions are guided by what is best for our community, not just for myself.

Chapter 5: Surrounding Myself with Allies

Looking back, I realize that the one thing that would have greatly helped me on my career path is self-confidence and strong women allies. It took time and experience to develop the belief in my abilities, some of that came from not having sponsors or mentors that were truly invested in me. Additionally, surrounding myself with strong women allies has made a tremendous difference in my agency and resiliency. The support and camaraderie we share have empowered me to navigate the challenges of the workplace with greater strength. I don’t feel alone and I can call upon a strong network to help me.

As I continue my journey, I am committed to making room for others at the table. I strive to foster an inclusive environment that encourages growth and amplifies diverse voices. By doing so, I hope to contribute to a pipeline of growth that uplifts individuals and propels our collective success.

Epilogue

My love for math has shaped my life in ways I never could have imagined. It has taught me to think critically, approach problems systematically, and find joy in unraveling the mysteries of the world. Through my career as a math teacher, data manager, and leader, I have found fulfillment in both sharing my knowledge and empowering others.

As I move forward, I will continue to champion gender equality and work towards dismantling the barriers that hold us back. I will strive to be the mentor and ally I wish I had when I was starting out. By embracing our unique strengths and fostering a supportive community, I believe we can create a more inclusive and equitable world for all.

Honestly, I do not really know when my passion for science, and in particular math first manifested itself. But from my experience, I can definitely say that being surrounded by the right people and mentors plays a big role in continuing in this direction and not steering towards following one of your other passions.

[..] in all of the career options that I tried, I was missing the logical and structured thinking and the challenges that math brings along.

My favorite subjects in high school had always been math and languages. It was after high school that I was thinking about combining the two subjects but I did not see myself becoming an elementary, middle, or high school teacher which probably would have been a natural choice. I tried several other options realizing internships and applying for study programs but in the end in all of the career options that I tried, I was missing the logical and structured thinking and the challenges that math brings along. It was after a gap year in Australia that I remembered one of my math middle school teachers telling me that I would be the right person to study math. Despite not agreeing with him at that point in time, in the end, I decided to give it a try. I went from a Bachelor’s to a Master’s to a Ph.D. degree in (applied) mathematics.

[..] I am very grateful for my choice as it allows me to not just learn more within my discipline but also about many others.

On the way, I kept learning languages and following my other interests especially learning more about other cultures and getting to know more of the world. After my Ph.D., I decided to go to the US for a postdoc where I stayed for about two years. Then I moved to Bilbao, Spain for another postdoctoral position. After almost two years there, I decided to stay in Spain and move to Madrid. This is what brought me to my current position. Currently, I am a postdoctoral research associate at IMDEA Materials. Here, I mainly develop models and algorithms for the acceleration of materials discovery for finding materials alternatives that are for example more sustainable. This means for instance that they are more inspired from nature, less toxic and do not deplete important limited resources. Having a background in applied mathematics, over the last 10 years I have had the opportunity to apply my mathematical knowledge in many areas reaching from cardiovascular stent design to optimization of fermentation processes to modeling cell metabolism to control of disease transmission dynamics to materials discovery. Looking back at my career decision, I think I would have been happy with studying computer science or engineering as well but it definitely had to be a science subject and I am very grateful for my choice as it allows me to not just learn more within my discipline but also about many others.

An academic research career can bring along a lot of frustration, uncertainty, and not always supportive environments but enjoying the process of learning from every experience, having the opportunity to make the world a better place, and following your passion make it worthwhile.

There have been tough phases and I definitely cannot say that I have never thought about switching careers. But I think that I have always enjoyed the challenges that my career path has brought along, maybe not always at the moment but overall, I believe that from facing challenges you learn the most. An academic research career can bring along a lot of frustration, uncertainty, and not always supportive environments but enjoying the process of learning from every experience, having the opportunity to make the world a better place, and following your passion make it worthwhile. Mentorship programs can give a lot of support on the way to keep you focused on your path and dealing with many of the given challenges. I am definitely very grateful for those mentors along the way that supported me and encouraged me to follow my passions.

If I had the opportunity to talk to my 20-year-old self, I would have told her: “Never regret anything, be grateful for the good things that every decision brought along, follow your passions, hold on to your core values, do not let your fears rule you and most importantly enjoy the process and live in the moment without holding on to the past or having fears about the future. You do not choose your destiny but you choose your company. You will find your way. Do not get lost in too much work, there are also other important things in life and remember success is one thing but you do not want to die one-day having regrets, such as not having shown enough care for your beloved ones and not having followed your other dreams and passions.”

Juliet Nakakawa Nsumba

Born in Kayunga district, Uganda • Birth year 1986 • Studied Mathematics and Physics (B.Sc. with Education) at Makerere University in Kampala, Uganda • Highest Degree Ph.D. in Mathematics • Lives in Kampala, Uganda • Occupation Lecturer at Makerere University

Currently, I am a lecturer in the Department of Mathematics at Makerere University in Kampala, Uganda. It is so exciting that today I consider myself one of Uganda’s most successful women in mathematics. At my primary level, I used to struggle with mathematics but was always intrigued by the challenges it would cause me to think about. I finished my primary level with mathematics as my worst subject. My secondary education was a turnaround. I would struggle with math until one time we had a change of teacher and he gave the first test. I got a 20%, and in the second test a 40% and after that my performance drastically improved and my passion for the subject grew so that it became my best subject. My math teacher encouraged me a lot. I had to redefine my friends to have those with similar interests. I would discuss this with my peers irrespective of gender. The reading of mathematics became easier.

Regarding the negative image that mathematics was for men: I guess I refused to believe that. I saw it as a challenge that had to be solved.

After my O’ level, resources were scarce in that my parents couldn’t afford my education at the kind of schools with equipped laboratories to enable me to continue pursuing my math/science career. But they were so determined to see me excel. My mom would always encourage me not to lose hope. At that time, I belonged to a supported program of Compassion International. That is where my help came from at the moment. God used Compassion to fully provide my sponsorship throughout A’ level. Of my A ‘level subjects, mathematics still seemed easy and would still be my best. Of course, I had support from my teachers who always encouraged me. Regarding the negative image that mathematics was for men: I guess I refused to believe that. I saw it as a challenge that had to be solved. I spent most of my time with the boys. Thank God they were quite helpful. When they noted I wasn’t going away, they knew we had to work together. When I completed my Uganda advanced certificate, I was given a Bachelor of Science degree with education (mathematics, physics). To be honest, I had never dreamt of being a teacher. I wanted to do Telcom engineering. My grades couldn’t push me there. Today I am grateful that my passion and desire for mathematics never came to an end. I decided to do my best to get good grades during my Bachelor’s degree. This opened more doors for me.

(…) I decided on mathematical epidemiology. I have seen so much of its application with endemic diseases and the consistent outbreaks of new viral diseases, especially in my country.

Later I joined the African Institute for Mathematical Sciences, which provided a platform for me to see how I could use mathematics. I have always loved the application of mathematics. It is not surprising that when I decided to choose the direction for my career, I decided on mathematical epidemiology. I have seen so much of its application with endemic diseases and the consistent outbreaks of new viral diseases, especially in my country. After my Ph.D. which I completed in my home country, I felt equipped to be part of the solution to our health sector. Yes, I am still growing in my career and every day I notice my effort in changing the lives of my people and Africa as a whole.

The limited resources never stopped me from pursuing my dream – instead, I would utilize whatever opportunity I could get to excel.

Being a mathematician has changed my status; by this, I cannot consider myself poor or financially disadvantaged, I have gained respect even among my peers just because I chose mathematics up to the highest academic qualification. As a mentor on several forums, I have got a number of young people who look up to me as their role model, something I lacked as I pursued the mathematics journey. I have inspired many to pursue the subject and STEM fields. I am an advocate for girls in STEM, and sharing my story with those young people struggling and almost giving up on mathematics is my passion. Once in a while, I do outreach programmes where I get to visit schools so that I can encourage young people that they can achieve much more as others before them have achieved. The mathematics journey is always interesting, but only those who choose not to give up can succeed. The limited resources never stopped me from pursuing my dream – instead, I would utilize whatever opportunity I could get to excel. The change of attitude and not dwelling on negativity from those around me enabled me to excel.

I always loved how neat math was. No matter the problem, the answers seem to come with a simple number. After taking partial differential equations and numerical analysis courses, it seems so silly now, the subject is anything but “neat”. It is complex, chaotic, and elegant, but what I have come to appreciate is its beauty, its ability to explain the world around us.

When I imagined a mathematician, I thought of an old man sitting in a flickering candle-lit room with melted wax and papers strewn around on an old wooden table. What did that really mean in the era of supercomputers, high-speed trains, planes and rockets?

As a child, I never really thought of being a mathematician as a job to pursue. I mean, to be fair the greats that I knew of only existed in Ancient Greece or Rome. When I imagined a mathematician, I thought of an old man sitting in a flickering candle-lit room with melted wax and papers strewn around on an old wooden table. What did that really mean in the era of supercomputers, high-speed trains, planes and rockets?

[..], I took the route of role models like Howard Wolowitz from the Big Bang Theory and Dr. Amelia Brand from Interstellar, and chose a degree in Aerospace Engineering.

So, when I had to choose a degree to study, I took the route of role models like Howard Wolowitz from the Big Bang Theory and Dr. Amelia Brand from Interstellar, and chose a degree in Aerospace Engineering. When I entered, I was excited by the engaging new problems I would learn to solve – whether it was in understanding rocket propulsion or in the use of orbital mechanics within navigation. However, instead I became bogged down with solving mundane structures and material problems. Moving into my sophomore year, classes did become more interesting with my first fluids and orbital courses. Every time I stepped into an engineering classroom, I felt a sense of excitement in understanding the fundamental equations, rather than the applications to real-world problems.

While I had once run away from engineering, I found myself right back to where I began, but instead I was in the role of a mathematician.

I reflected on my prior math courses, thinking about how I would apply these geometric properties and analysis techniques to problems that I had been introduced to in my aerospace courses. I knew it was time for a change, so I switched gears to classes like complex analysis, partial differential equations, and introduction to proofs. I was hooked. Around the same time, I had my first laboratory experience in mathematics. I spent the summer working on neural networks to reduce the loss from the 2D approximations to the advection-diffusion equation in transport phenomena. It was one of the hardest learning experiences, coming in with very little knowledge of Deep Learning, but the hours spent on literature reviews seemed less like work and more like unravelling my favorite mystery novel. This was the moment in which the puzzle pieces of all my interests across engineering and mathematical disciplines clicked.  So when I finished my summer project, I immediately looked for new opportunities in applied mathematics, and I was fortunate enough to find a supervisor in the Electrical and Computer Engineering department to work on Finite Element Methods and the Schrödinger equation. While I had once run away from engineering, I found myself right back to where I began, but instead I was in the role of a mathematician. My supervisor has helped me find confidence in my abilities and given me the opportunity to take lead on my first project, and is the reason I have found the confidence to apply to applied math MS/PhD programs for fall 2022.

I had women like Katherine Johnson to look up to, but she was merely a role model, not an individual I could tangibly connect to.

While I have been undoubtedly lucky to be surrounded by amazing mentors, the lack of women mathematicians and engineers did not go unnoticed. I found my experiences to be hardly unique. When talking to a good friend in the math department, I found that she too had been the only woman in her math classes. In four years, I had only had one woman math professor and one woman graduate student that supervised my research. In my graduate and advanced courses, I was one of two or maybe three women students. The world had long moved away from the old man in the candle-lit room, but the representation of women in the industry was grossly underdeveloped. Looking at research faculty in the graduate programs I applied to, I found the representation to be quite similar. I had women like Katherine Johnson to look up to, but she was merely a role model, not an individual I could tangibly connect to. She seemed just as far remote as the Greek greats.

Inequality seems to be quite an abstract notion and equality just an idealized concept, existing only in philosophical treatises. To encourage more women to pursue a career in academia and research, we must begin by creating real mentor-mentee relationships that go far beyond the professional. Only through this tangible bond can we expect to see true equality in every field, including this complex and elegant language we hold so close and I sincerely hope that one day the word mathematician comes with an image of a woman and a man working side by side in a world intertwined with modern technology.

Born in Tema, Ghana • Studied Mathematics at the University of Glasgow, UK • Highest Degree PhD in Mathematics • Lives in Accra, Ghana • Occupation Lecturer

Growing up in Accra, Ghana, I loved mathematics. I found joy in solving mathematics questions but I did not envision a career in mathematics as a thing for me. My older sisters studied business courses at the university so I decided to follow in their footsteps and applied to study Business Administration as my first choice course at the University of Ghana. Fortunately or unfortunately, I could not gain admission for my first choice program and had to settle for my second choice which was mathematics and economics. Nevertheless, I loved the challenge mathematics presented. I had to spend hours after lectures revising lecture notes and solving exercises. I found this thrilling.

My motivation for giving back to the community where I grew up was to give students from less privileged backgrounds access to quality education.

After undergraduate studies, I went to the African Institute for Mathematical Sciences (AIMS) Ghana for postgraduate studies. It was at AIMS that I got exposed to different fields of mathematics. From AIMS Ghana, I went to the International Centre for Theoretical Physics (ICTP) for a postgraduate diploma in mathematics. The program at ICTP was very challenging but it helped convince me that I could pursue mathematics further.

After postgraduate studies, I became conscious of the opportunities available when one studies mathematics. Prior to this, most of us thought anyone who studied mathematics at the university would end up as a teacher. This is not to say that teaching is not a good profession, I love teaching. When I realised the many opportunities available after postgraduate studies, I volunteered as a mathematics teacher in a junior secondary school in my community. This would inspire the young students that mathematics is not impossible to study as perceived and one could pursue a career in mathematics. In subsequent years, I volunteered as a mathematics teacher for at least a month and donated books to the library of this school. My motivation for giving back to the community where I grew up was to give students from less privileged backgrounds access to quality education.

My research interest is in noncommutative algebras which are abstract analogues of subtraction and division.

I was awarded a Schlumberger Foundation Faculty for the Future Fellowship in 2015 to pursue PhD in Mathematics studies at the University of Glasgow (UofG). In 2019, I graduated with a PhD in Mathematics from UofG, returned to my home country Ghana and started working as a postdoctoral fellow at AIMS Ghana. I am currently a research associate and academic manager for the Girls in Mathematical Sciences Program (GMSP) at AIMS Ghana. I decided to pursue a career in academia because I love teaching and doing research.

A summary of my research interest is as follows. Consider the operations of addition and multiplication, it does not matter the order in which you perform them. That is, 2 + 3 = 3 + 2 and 2 × 3 = 3 × 2. In mathematics, we call this the commutative property. However, the operations of subtraction and division are not commutative. That is 2 − 3 is not equal to 3 − 2 and 2 ÷ 3 is not equal to 3 ÷ 2. We say that subtraction and division are noncommutative. My research interest is in noncommutative algebras which are abstract analogues of subtraction and division. For any shape that you can draw on a flat surface whereby the shape can be described by an equation, we investigate whether we can put a noncommutative structure on the shape to make it a quantum homogeneous space. This area of research is abstract but our hope is that there will be useful applications of our results in a few years time.

Our mission is to inspire young girls about the diverse career options available when you study mathematics and our vision is to see girls being confident to pursue a career in mathematics and related fields.

I am passionate about supporting and promoting women in mathematics which ties in well with my new role as the academic manager for the GMSP. The GMSP is a hybrid 9 month program for high school girls from Ghana to nurture their talents in the mathematical sciences. We meet students monthly online for masterclasses with experts in different fields of mathematics. Then during vacations from school, the students visit the AIMS Ghana campus for residentials where minicourses in mathematics, industrial visits, interactions with mentors and extracurricular activities are undertaken.

I am also the founder of Femafricmaths, a charity that promotes female African mathematicians. We host guests by interviewing them about their journeys with mathematics and share the videos on the Femafricmaths social media pages. Our mission is to inspire young girls about the diverse career options available when you study mathematics and our vision is to see girls being confident to pursue a career in mathematics and related fields.

There are few of us and we need to ensure that barriers are removed so more women can pursue careers in mathematics.

Mentors have played a critical role in my academic and professional journeys. Ken, Ulrich, Prince and Chelsea have been phenomenal mentors who mentor me every step along the way. I have also benefited from the Women in Noncommutative Algebra and Representation Theory (WINART) research group. This is a collaboration between women in mathematics from different universities. I learnt a lot working with this research group comprising both early career and established mathematics.

It is important to be intentional about creating opportunities for women in mathematics. There are few of us and we need to ensure that barriers are removed so more women can pursue careers in mathematics. I was awarded a Schlumberger Foundation Faculty for the Future Fellowship for my PhD studies. This fellowship is for women in STEM from developing countries to enable us to study at top universities abroad and return to our home countries to support teaching and research. It would have been challenging to find other sources of funding for my PhD if I had not been awarded this fellowship by the Schlumberger Foundation.

Born in Guadalajara, Jalisco, Mexico • Birth year 1983 • Studied Mathematics at University of Wisconsin, Milwaukee in Milwaukee, WI, USA • Highest degree PhD in Mathematics • Lives in North Adams, MA, USA • Occupation Mathematics Professor

My love for math faded during my high school years. Being undocumented, living in the United States was challenging. Even though I was doing well academically, I thought I might never have the opportunity to attend college. I was sad, and at that time I turned to art as an outlet to deal with the challenges I was facing. I spent most of my senior year in high school in an art studio. I spent countless hours learning to draw, paint, and sculpt. I even dropped out of my calculus class just so that I could have more time to do art. I do not regret that choice, even though going a year without math courses hurt my mathematical skills. At the time, I needed something to help me deal with the anxiety and sadness I was experiencing, and art served me well. 

There I had a meeting where my mentor said “when you go to graduate school”. I had no idea what graduate school was, but I knew that if she believed in me, then I should go to graduate school.

After graduating high school, I was able to enter community college. How that was possible is a story for another day, but the main thing is that, upon entering the program, my mathematical skills were well below calculus. My first college math course was intermediate algebra, where I (re?)learned how to factor polynomials. I vividly remember that day’s lesson where the professor said “To factor x^2+5x+6 we need to find two numbers that add to 5 and multiply to 6.” I immediately raised my hand, proudly announcing that numbers did not do that. How can two numbers multiply and add to something different? Luckily, the professor was very kind and she allowed me to think of examples. After discovering that 2 and 3 did the trick, I felt such joy in understanding something that I had taken for granted: numbers are amazing and in fact multiplication and addition are two distinct things! From there my story began to take shape. 

After intermediate algebra I took all of the math courses the community college offered and later transferred to a four-year college to continue studying math. There I had a meeting where my mentor said “when you go to graduate school”. I had no idea what graduate school was, but I knew that if she believed in me, then I should go to graduate school. So, on I went! 

My professional mission is to ensure that mathematics is a welcoming place for everyone, and I am eager to keep working on this for as long as I live.

I always knew that I would like to be a teacher. There is something so beautiful about seeing someone understand something. Most people call that an “aha” moment, and it truly is special. I also knew that education is a path out of poverty and into opportunity. Being an immigrant, I knew firsthand that having options is one key component to a happy life. So, I have always wanted to help others reach their goals and attain their dreams. However, it was not until almost the completion of my PhD that I decided to be a college professor. Finding this as a career option was great because it has allowed me to continue learning while doing research and teaching students. Creating new programs and platforms that provide mentorship and support for students from groups who have been historically excluded from higher education has also been deeply fulfilling. This outreach work keeps me grounded and reminds me that there is still a lot of work to be done in order for everyone to have meaningful and positive experiences with mathematics. My professional mission is to ensure that mathematics is a welcoming place for everyone, and I am eager to keep working on this for as long as I live. 

Throughout those early years I could have used a larger community of support and to see others like me occupy positions and careers like those I had an interest in.

Being an immigrant, previously undocumented, and a Latina woman meant I rarely saw people like me in mathematics. Throughout those early years I could have used a larger community of support and to see others like me occupy positions and careers like those I had an interest in. Sadly, it took a long time to find a community of scholars who shared similar backgrounds and heritage. Yet this motivated much of my past work and inspired me and Drs. Alexander Diaz-Lopez, Alicia Prieto Langarica, and Gabriel Sosa to co-found the organization Lathisms: Latinxs and Hispanics in the Mathematical Sciences. Our goal is to share and amplify the contributions of Latinx/Hispanic scholars in math. We do this through a variety of means including Hispanic Heritage Month (in the US it is celebrated between September 15 and October 15) events, a podcast, and even a new book — Testimonios: Stories of Latinx and Hispanic Mathematicians. The book’s chapters will be freely available one per month starting in September 2021 and our hope is that this book provides a way for those within the community to learn of our stories while also giving advice to those who want to learn more about us and how to support our work. Although there is much work to be done so that those from historically excluded groups feel valued and uplifted in mathematics, I am hopeful that initiatives like Lathisms are making this reality possible.

My math story started with questions, as many other math stories, I suppose. In the early years of high school, math exercises were fun and challenging. I enjoyed solving them, but I never thought I would study math as a career years later. By that time, I wanted to become an engineer, like my dad, and hopefully work at a hydroelectric power plant. But somehow, math was like gravity, and I felt more and more drawn to it. Hence, I decided to study math at Escuela Politécnica Nacional in Ecuador at the end of high school. Looking back on it, I think I was lucky. Pursuing a career in math was not common in Ecuador. I had the support of my parents and I also was encouraged by my math teacher. However, I had no idea of what math was really about.

I enjoyed the vitality of the formal math language, which brings the possibility to precisely describe a deduction process and articulate a definition from an intuitive notion.

I found the early stages of my undergraduate studies challenging and, sometimes, difficult. However, I was amazed and triggered. I enjoyed the vitality of the formal math language, which brings the possibility to precisely describe a deduction process and articulate a definition from an intuitive notion. The beauty of the simplicity and richness of math made me stay. Nevertheless, the inflection point in my math story happened when I started to work as a research assistant in a project at the Research Center for Mathematical Modeling in Ecuador, ModeMat. In this project, I worked on the numerical solution of visco-plastic fluids. These fluids have a dual behavior; they move like a solid or like liquid depending on the stress imposed on them. I found the mathematical formulation of these fluids fantastic. In this process, I learned the fundamental laws underlying fluid dynamics, optimization methods and I improved my coding skills. This was the starting point of a journey that led me through a Master’s program in Mathematical Optimization and then, like the flow of a Newtonian fluid, to the Ph.D. program in Applied Mathematics. Being part of the Research Center, ModeMat, has shaped part of my life. I have grown up there from an undergrad student to a Ph.D. student under the supervision of four great advisers: Pedro, Sergio, Juan Carlos, and Luis Miguel. Their guidance during the Ph.D. has been essential and valuable. 

I am confident things are changing. At the moment, in my Ph.D. program, we are more women than men.

Nonetheless, I have realized that every time I was part of an international conference, unconsciously I ended up choosing a woman from the Academy as a role model. This unaware action, years later, made me realize how important visibility is. There were few academic women at the math department while I was an undergrad student; therefore, I had the chance to only have one math woman professor. I am confident things are changing. At the moment, in my Ph.D. program, we are more women than men.

I am in the last year of the Ph.D. This journey has not been like the stream of a calm river. Like a visco-plastic fluid, sometimes I have moved like a solid, slowly and without any change in my progress and, sometimes, one just flows like a liquid in a stream of exquisite results. The chance to write about my story came in an opaque moment of uncertainty and lack of confidence. It took me a while to sit and write it down. However, I have genuinely enjoyed it. This retrospective exercise helped me to reconcile and reconnect. Right now, I am focused on this last year of the Ph.D. and interested in a Postdoc. My thesis is still related to visco-plastic fluids. Therefore, in some sense, I think I kind of accomplished my teenage dream. I am not working at a power plant driven by water but I have a better understanding of the fluid dynamics laws to comprehend the power of water. Finally, I would like to take the final words of Natasha Karp’s math story (which I enjoyed a lot reading) as advice: “Enjoy your journey but don’t expect to know exactly where you are going and keep growing and challenging yourself’’. I think that’s what I will do.

To be honest, I don’t really know where my fascination with maths has come from. None of my family members are doing anything related. But I remember an instance in first grade where we had a small test on multiplication tables and I got quite competitive to be the first one to finish. I think at that point I decided that I wanted to be good at maths. This didn’t really carry through all my school years, but maths kept being a subject I enjoyed. I became more interested again in secondary school when one of my teachers involved me in a maths club. Another student and I started working on a small project together which we presented at a youth research competition. This was probably the first time I really sat down and used the maths I’d learned so far to solve a specific problem. We ended up winning the local round. Ultimately, I think the support and affirmation from my teachers during my school years gave me the confidence to believe I was good enough to go on and study maths.

It fascinated me that there were highly applied fields of this very theoretical subject I was studying, and I started hoping I’d later find a job like that.

After high school I went off to university excited and full of energy, just to realise in the first two semesters that studying maths was a lot harder than I anticipated. I barely passed my exams even though I had studied a lot. It was a big adjustment to the different way of thinking, and I needed to figure out what to focus on in order to pass my classes. However, in my mind there was no option to quit. I guess my competitive side from first grade came out and I saw it as a challenge to finish my Bachelor’s. Things got better eventually, especially when we started electing more specialised courses. Throughout, there were always little things that got me excited again about doing maths. Our department organised events every semester where alumni came to present the work they do now and the companies they work for. I remember someone talking about his work in imaging and the connection of mathematics and image processing. It fascinated me that there were highly applied fields of this very theoretical subject I was studying, and I started hoping I’d later find a job like that.

“Don’t compare yourself too much. Focus on the work you’re doing and dare to go for the things that fascinate and excite you even if you don’t believe you’re capable of achieving them, yet.”

During my Master’s, it became less about just getting through the degree and more about finding interesting courses and projects. The classes were smaller, and we had more contact to the lecturers. After one of my oral exams, I was asked about my plans and what I wanted to do next. I was startled, because I didn’t quite understand why a lecturer would be interested in this. I told him that I wanted to do an internship somewhere in industry before finishing my degree. I still didn’t have a clear idea of what I wanted to do after my studies, so this seemed like a good start. He offered his support in finding an internship position. Half a year later I summoned up all my courage to chase him up on his offer and asked if he’d know a company that would take interns to work in medical imaging. I think this got the ball rolling to get to where I am now. Through his and another professor’s support I started an internship at the university and with the supervisor I am doing my PhD with now. It is still astonishing to me that it took so little as a question, to start figuring out where I wanted to go next. The research group I did my internship at was very welcoming and many shared their stories and decision-making processes with me. This probably influenced me the most. From the outside you often just see these really smart people producing amazing work. But for me it was more encouraging to see their struggles and understand that in order to do a PhD you weren’t expected to know everything already or to be a genius. I think this would also be something I’d tell my 19-year-old self before going to uni. “Don’t compare yourself too much. Focus on the work you’re doing and dare to go for the things that fascinate and excite you even if you don’t believe you’re capable of achieving them, yet.” I guess it’s something I’m still learning to this day. But I have found a group of amazing women that remind me we’re all doing the best we can, and a great research cohort that is encouraging with all the small achievements.

Born in Germany • Birth year 1987 • Studied Mathematics in Münster, Germany • Highest Degree PhD in Applied Mathematics from the University of Cambridge, UK • Lives in Düsseldorf, Germany • Occupation Scientific Associate

My decision to study mathematics was anything but straightforward. I always enjoyed maths classes throughout my primary and secondary school years. I also have to add that I personally believe this experience was significantly influenced by the fact that I had great maths teachers. Luckily, against a sadly very common (mis)perception of society I never felt that maths was not for girls. Maybe this was unconsciously strengthened by the female maths teachers I had in early school years. Shortly before my last two years of secondary school began, I decided against choosing mathematics as a major (which always seemed to be clear beforehand) because I did not enjoy the maths classes I attended in the preceding year. Nevertheless, I very much enjoyed the following two years of maths classes, which is among other things certainly due to the amazing teacher (and possibly first maths mentor) I had. From the beginning, he made quite clear that he did not really understand why I only chose maths as a minor, but he would motivate, encourage and challenge me even more throughout the two years. He also was one of the few persons I could consult when I was thinking about applying to study maths at university.

In the end, (…) I decided to study maths but was pretty much clueless about how a typical workday of a student even looked.

I was the first family member to attend university, let alone having received a university-entrance diploma, and so my family could not really provide me with a lot of advice or experience in this regard. However, they were incredibly supportive in multiple other ways throughout my studies and without their support I certainly wouldn’t be where I am now.
In the end, after considering other options such as linguistics and language studies, I decided to study maths but was pretty much clueless about how a typical workday of a student even looked. At first, I thought it was sufficient to attend the lectures (like the classes in school) and go home after. This also fit snugly with the hours I had to work in my side-job. The ‘homework’ was surely very similar to the one at school and I would just solve the mathematical problems we were given by myself like I did in school. Preparing for the exams would certainly be similar to schooldays and I would not have to study too hard. It did not take too long until I realised that I was completely wrong. The first unsuccessful exams hit me quite hard and ultimately, I found myself in a situation that I had not known up to this point in my life. It was already pretty late to turn things around completely and after many thoughts and conversations, I decided to start all over again one year later.

It is essential to have role models to look up to from the beginning and ideally to be mentored and supported by experienced and committed persons. I am extremely lucky and thankful to have those people in my life.

The further I got and also the more I was able to specialise in my studies, the more I enjoyed student life. I was lucky enough to have a strong and supportive network of fellow students and friends. What is more, especially in the final year of my Bachelor’s, I had two extremely dedicated, passionate and encouraging advisers, one of which was going to become one of my main mentors throughout my academic career. And this is the main message I would like to convey here. It is essential to have role models to look up to from the beginning and ideally to be mentored and supported by experienced and committed persons. I am extremely lucky and thankful to have those people in my life. In addition to my Bachelor’s and Master’s supervisor, I had two incredibly supportive, heartening and inspiring women as a PhD supervisor and co-supervisor. I believe that my passion for women encouragement was significantly influenced by my main PhD supervisor who herself has given numerous talks on her own experiences as a woman in maths, her career path and her very personal journey to become an excelling mathematician and leader.

We realised that we were not alone with our struggles and doubts and this was extremely liberating and empowering.

Already during my Master’s, I participated in a mentoring programme that was coined by a very committed (male!) diversity officer at our maths department. We had regular meetings in small groups of three mentees and one mentor who was a female PhD student. We were able to informally chat about positive and negative experiences, the decision whether to continue as a PhD student or search for a job in industry and how being a woman in a still male-dominated field poses some challenges. We realised that we were not alone with our struggles and doubts and this was extremely liberating and empowering.

Without all of this amazing support and encouragement I am 100% sure that I would not have continued doing a Master’s respectively PhD respectively post-doc, as I have fairly often thought about quitting at various points in my career. In the end, persevering, listening to my mentors and believing in myself was worthwhile. Nowadays, I try to identify situations in which I observe sexism, female students and colleagues struggling with imposter syndrome, or simply the exhausting and competitive environment that academia sometimes is. Then I try to speak out or even manage to become a mentor myself.

My PhD research was in applied mathematics. More specifically, in one of my main projects I developed mathematical image analysis tools for an application in cancer research. In an interdisciplinary collaboration I worked with biologists that studied the efficacy of anti-mitotic drugs trying to slow down or prevent mitosis, the process of cell division, in cancer cells. I developed a graphical user interface that facilitated the automatic analysis of sequences of microscopy images showing the treated cells over time.

I loved the communication part of post-grad academic life; not only discussions and exchanges, but also communicating my work to others at conferences, workshops and during outreach projects. 

I always liked collaborations in my academic career and I believe that against all stereotypes, at least applied maths is a very team-oriented discipline and it is essential to discuss lectures, papers and ideas with fellow students and colleagues. I loved the communication part of post-grad academic life; not only discussions and exchanges, but also communicating my work to others at conferences, workshops and during outreach projects. Recently, I even quit research and started working as a scientific associate at university focusing on science communication as well as education.
