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.

Through all my school years I have always felt that the more logical reasoning the subject involved, the more attention it would capture from me. I remember being the one helping out my colleagues preparing for math exams and being supported by others with the subjects of social studies. Although as a child I enjoyed very much pretending I was a teacher, assigning the seats to the dolls, I grew up hearing that it was an underappreciated profession in my country, with which people usually feel overworked and underpaid. Even after finishing high school I was very resistant to choose mathematics and teaching as a career, but I finally decided not to walk away from my dream role. The only (probably naive) argument for that was that I have always enjoyed studying mathematics.

While adjusting myself to the new life in a very large city and struggling with the exams, this period was one of the toughest in my academic career but also the first step towards professional maturity in research/academia.

Only when I got to the university for my bachelor in mathematics, I realized that I could perform poorly in a math exam, which was unfamiliar to me. I accepted the challenge and worked hard to finally achieve good results, especially in the more abstract courses. Algebra was particularly demanding, with a very tough and inspiring female professor. She often provided us with a lot of extra reading materials and required us to attend extra lectures, jointly with her graduate students. But since she was always willing to provide us with assistance, I felt very challenged and also wanted to get along with her. That pushed me to put a lot more effort into my studies. As a result, I decided to pursue a Master’s degree in a different city, at one of the best universities in the country. While adjusting myself to the new life in a very large city and struggling with the exams, this period was one of the toughest in my academic career but also the first step towards professional maturity in research/academia.

The math-life balance also comes as a challenge, while trying to fulfill the pressure to be productive and achieve personal goals outside work at the same time.

My years of PhD and postdoctoral studies were used as an opportunity to perform my research under different scientific atmospheres, in some different centers in Brazil and abroad. The interaction with different research members and visiting fellows provided me with an enriching scientific experience, giving me the opportunity to engage in collaborations within my field of research. As luck would have it, I ended up having a very kind and talented professor working in nonlinear dynamical systems as my PhD supervisor. That period was, however, one of the hardest and exhausting periods of my academic life. Not only for the strong gender imbalance in mathematics but also for recurrently having no sense of belonging. The hard side of leaving the comfort zone, especially coming from humble backgrounds, is the general feeling that you are not as capable as your peers. At that point, one is also confronted with the fact that besides the technical scientific abilities, it is also necessary to manage other required skills of your career. Critical thinking, presentation and communication abilities, self-discipline, leadership and advising skills, among others, also came in handy. The math-life balance also comes as a challenge, while trying to fulfill the pressure to be productive and achieve personal goals outside work at the same time. All of that requires time, maturity and, more importantly, a great support in order to overcome the challenge.

In this journey, I realized that besides the urgency of creating an equitable world in the near future, where underrepresented groups don’t have to deal with biases in and outside the workplace, it is also crucial to find a stimulating and safe environment to work in. To do so, it is very important to be surrounded by like-minded peers and colleagues you can trust to talk about the work and insecurities inside academia. Taking advantage of all professional and personal opportunities and resources is also essential.

Born in Oñati, Basque Country, Spain • Birth year 1984 • Studied Mathematics at Universidad del Pais Vasco/Euskal Herriko Unibertsitatea (UPV/EHU) in the Basque Country, Spain • Highest Degree PhD in Mathematics at UPV/EHU • Lives in Oñati, Basque Country • Occupation Math teacher and Yoga teacher

Curiosity and desire to know are words that describe me quite well. I have always asked myself a lot of questions about everything, and this also happened to me in Math classes, specially in high school. I wanted to know more, go deeper, make sense of all the abstract notions that we were learning. I was the annoying student that asked the uncomfortable questions to the teacher. But I never considered to study Math. Actually, my idea was to study Physical Education, since sports have always been an important part of my life and understanding the biomechanics of the human body has always interested me a lot.

It was my school counsellor who encouraged me to study Math. At the beginning I did not see it very clearly. I thought that I did not fit in with the mathematicians’ stereotypes that I had in my mind. I thought that it would be too hard, that I would have to study so much that it would be difficult to combine with my sport life, since I was playing in a handball team and did not want to give it up. But at the same time this idea appealed to me a lot and I decided to give it a try.

I really enjoyed my undergraduate studies at university. I fell in love with Math. I met wonderful people. Although it was not my plan, thanks to an amazing female professor, I decided to embark on the PhD journey. They were beautiful years, with ups and downs, in which I had the opportunity to travel a lot, to live in different places, to meet many people, to expose myself to new experiences, to learn a lot about Math and also about life, to get to know myself better. It was a rich adventure. I am very thankful that I had the privilege to experience this journey.

It was not an easy decision, but after 8 years since I started my Master, I decided to take a break and I quitted my short scientist career.

After my PhD, I went to Helsinki to work as a postdoc. It was there where I discovered Yoga, and I started asking even more questions about everything in general. I spend few years trying to fit in the lifestyle of academia, trying to find a way of being coherent with myself, my will and my feelings, dealing with millions of doubts about how to find the balance between my personal and my professional life. It was not an easy decision, but after 8 years since I started my Master, I decided to take a break and I quitted my short scientist career.

For me, Yoga and Math are very related. Both try to answer the existential questions of life, each discipline from its own point of view.

Since then, I have been very involved with Yoga. It has become in an essential part of my life. I founded a Yoga studio together with one of my friends in my hometown. For me, Yoga and Math are very related. Both try to answer the existential questions of life, each discipline from its own point of view. Both are abstract and awaken your inner imagination. Both disciplines give you very useful tools to manage your everyday life and to deal with everything that happens in life.

Nowadays, in addition to teaching yoga, I also teach Math at the university. This combination is a good balance for me. I do not know exactly what my future career path will be, but it is clear to me that in one way or another mathematics will be there. If you have a call to study Math, I would like to encourage you from the bottom of my heart. It will be enriching in all aspects of your life.

Born in United Kingdom • Birth year 1974 • Studied Biochemistry at Warwick University in United Kingdom • Highest Degree PhD in Chemistry from University of London • Lives in Cambridge, United Kingdom • Occupation Director Biostatistics at AstraZeneca

I really struggled at school in the early years, particularly with reading and writing; but then when I was around 12, it started to make sense. I was formally diagnosed as being dyslexic when I went to university, I guess when I was 12  things clicked into place as I found my strategies to get round my dyslexia. Those early years of struggling and being in bottom sets has left me with feelings of doubt but also a drive to prove people wrong. At 16, I selected mathematics with statistics, biology and chemistry as my specialist subjects and got the highest grades possible. I really enjoyed statistics and mathematics, and used to do extra work for fun. However, it was taught as a theoretical subject and I had no sense of what you could do with it. I also had no role models; I am the only person in my family to graduate from university. If you were a clever woman, you became a teacher or a doctor. Being a doctor didn’t appeal, so teaching became the ambition and I decided to study biochemistry with a year in industry at Warwick University and graduated with a first-class degree.

After I conducted some experiments, I felt the mathematical techniques used to make decisions were poor. Consequently, I started studying statistics (…).

I really enjoyed my year in industry, where I learnt the fundamentals of research, but after years of conditioning that my path was to be a teacher, I then trained as a secondary school teacher. After a couple of years teaching, I realised that I didn’t feel satisfied intellectually. I was working hard but didn’t feel I was growing. I decided to return to science and was offered a role back with the industrial placement company who sponsored me to complete a PhD in partnership with Imperial College, London. Unfortunately, the company folded but I just managed to complete my PhD. My confidence as a scientist felt low, I felt I had snuck in my PhD and I decided to work in academia to prove myself and joined the Cambridge Centre for Proteomics as a post-doc. I was very lucky and given a lot of freedom. After I conducted some experiments, I felt the mathematical techniques used to make decisions were poor. Consequently, I started studying statistics and writing papers exploring experimental design and data analysis for proteomic experiments. I was flying high and had 12 publications but then my first son was born and he was very poorly and I had to prioritise the family. I found a part-time job as a biostatistician with the Wellcome Trust Sanger Institute supporting in vivo research. It felt like I was starting again but I could meet my family needs and keep working. Over time, my son got better. The new environment gave me new opportunities; for example, I spent some time with database experts who helped me learn to code. I started publishing again in data analysis and experimental design for in vivo research. There wasn’t permanent funding in academia for this type of role so I applied to AstraZeneca, who had just relocated to Cambridge, as a statistician.  

I feel my dyslexia is a strength, as it helps me see the bigger picture, connect ideas and be a better manager.

What am I doing now? I now lead a team of statisticians for AstraZeneca supporting preclinical research. I still work part-time (80%) to meet my family commitments. The work is very varied and we have the opportunity to make a big impact. We jump into projects, assist the scientists, enable their research and then jump to the next project. I find it surreal that I, a self-taught statistician, lead these amazing statisticians. I feel my dyslexia is a strength as it helps me see the bigger picture, connect ideas and be a better manager. As a dyslexic woman who has an unusual career path I bring diversity to the leadership element of my role. I also give lectures around the world on my research topics of interest and get the opportunity to work outside of AstraZeneca on working groups exploring topics such as sex bias or reproducibility. I love my job. It is applied statistics having impact.

As an individual with imposter syndrome, you have to recognise your voice of doubt but not let it control you.

My career path has had many twists and turns. That is real life. There are benefits, I have more experience to draw upon. I feel my journey shows there isn’t one path that is right for you. You should be open to opportunities and change. Change is positive. You do have to be prepared to take risks. As an individual with imposter syndrome, you have to recognise your voice of doubt but not let it control you. From the perspective of maths, data is everywhere, being good with data is such a strength. You don’t have to be a theoretical expert to add value and have impact. Enjoy your journey but don’t expect to know exactly where you are going and keep growing and challenging yourself.
