Born in El Kef, Tunisia • Birth year 1996 • Studied Applied Mathematics at University of Tunis El Manar in Tunis, Tunisia • PhD in Applied Mathematics from University of Tunis El Manar in Tunis, Tunisia • Lives in Tunis, Tunisia • Postdoctoral Researcher at University of Tunis El Manar in Tunis, Tunisia

I was born in El Kef, in the northwest of Tunisia. My city has been known as the “City of Love and Beauty” since Roman times. It is a culturally rich place where art feels naturally present in everyday life: in the streets, in the shape of the country, in the way people speak, and in how different people live together. To me, it feels like art, like a special world. Growing up in such an environment deeply shaped the way I perceive the world as a big garden. A garden needs many different types of flowers to be truly beautiful, just like the world needs different people, cultures, and perspectives. With respect, love, and care for one another, this garden becomes even more beautiful.

A garden needs many different types of flowers to be truly beautiful, just like the world needs different people, cultures, and perspectives.

Mathematics has always been at the center of my life. From an early age, I enjoyed working with numbers and solving problems mentally, and I often saw the world as a collection of problems, each with its own strategies and solutions. I chose mathematics as my academic track during high school, and after obtaining my baccalaureate, I continued to pursue mathematics, as I have always been passionate about it.

I consider mathematicians to be artists in their own way: they express creativity through research, abstraction, teaching, and problem-solving.

If I had to describe what makes me happy, I would say: mathematics and flowers, and even more, the idea of bringing both together. For me, there is a deep connection between mathematics and art. Flowers represent natural beauty, harmony, and simplicity, while mathematics provides the tools to understand, describe, and structure that beauty. Mathematics transforms complexity into clarity, while art expresses meaning beyond words. I consider mathematicians to be artists in their own way: they express creativity through research, abstraction, teaching, and problem-solving. In this sense, mathematics is not only a scientific discipline but also a form of artistic expression.

A meaningful milestone in my journey was participating in the Heidelberg Laureate Forum 2025, an annual international gathering where 200 outstanding young researchers in mathematics and computer science spend a week engaging with the world’s most prestigious laureates. Blending scientific dialogue with meaningful networking, the Forum creates a unique space for inspiration, mentorship, and the exchange of ideas, shaping the next generation of innovators. During this experience, I had the opportunity to present my artwork: “تونس من حدودها نعيد رسم الأعماق” (“Tunisia From Its Boundary We Redraw Its Interior”).  

This artwork reimagines Tunisia as a Calderón inverse problem, a problem where one attempts to reconstruct the internal structure of an object using only information measured at its boundary. In my artwork, it means reconstructing a nation’s soul using only its borders. Tunisia is not just land enclosed by lines, it is emotion, culture and history expressed along every edge. Inspired by Queen Dido’s legendary optimization problem, the artwork reflects the power of geometry, identity, and feminine genius.Tunisia is a country of art and culture; its borders are the key to understanding its identity. In this regard,Tunisia can be seen as a perfect inverse problem. To understand Tunisia, we must study its borders mathematically and with our heart. This experience allowed me to merge my mathematical mindset with artistic expression, and to share a personal vision that connects identity, culture, and creativity.

I’ve always wanted to understand my father’s brain injury and for this reason now I am interested in biomathematics.

A defining moment in my life came when my father had a serious accident at a young age, which caused him to lose his memory. He no longer recognized me as his daughter. This deeply affected me and led me to question the functioning of the human brain and memory. This personal experience motivated me to pursue science with determination and to better understand complex systems. I’ve always wanted to understand my father’s brain injury and for this reason now I am interested in biomathematics.

During my PhD at LAMSIN (Laboratory of Mathematical and Numerical Modeling in Engineering Sciences), I worked in the field of inverse problems, which focuses on recovering unknown information from observed data, exploring both its theoretical and applied aspects. I did not fully answer the questions that motivated me, since understanding a system as complex as the human brain is a huge challenge, but the journey gave me strong analytical and research skills. 

As a PhD student, I also had the opportunity to complete an internship at BCAM (Basque Center for Applied Mathematics), where I worked on real-world problems in an international research environment. This experience was particularly valuable, as it allowed me to apply mathematical tools to practical situations and collaborate with researchers from different backgrounds. Conferences, summer schools, and workshops, where I exchanged ideas with other researchers, strengthened my interest in research and confirmed my desire to pursue an academic career that combines both teaching and research. Teaching at National Engineering School of Tunis (ENIT) during my PhD has been one of the most fulfilling aspects of my journey: I enjoy explaining concepts and helping others understand mathematics, and sharing knowledge gives me a sense of purpose.

Mathematics has taught me how to think logically, analyze complex situations, and break down difficult problems into simpler components. It is a powerful tool for understanding real-world phenomena (…).

Today I am a postdoctoral researcher, continuing to develop my research skills, and working on advanced mathematical problems. My work today is strongly connected to the foundations I built during my studies. Mathematics has taught me how to think logically, analyze complex situations, and break down difficult problems into simpler components. It is a powerful tool for understanding real-world phenomena and contributing to fields such as healthcare, economics, and engineering.

I am particularly interested in biomathematics, where mathematics is used to study biological systems. I aim to contribute to research that helps better understand complex systems such as the human brain and diseases.

As a woman in STEM and as a woman from Africa, I believe that talent exists everywhere, but opportunities are not always equally distributed.

As a woman in STEM and as a woman from Africa, I believe that talent exists everywhere, but opportunities are not always equally distributed. Women often have to work harder to be recognized, and representation in many scientific fields is still limited. My journey reflects both personal determination and the broader context of striving for excellence in environments where opportunities are sometimes limited. This identity has strengthened my resilience, ambition, and sense of purpose.

I believe that achieving gender equality in STEM starts with changing mindsets and ensuring equal opportunities. Encouraging girls to pursue STEM is important, but it is equally essential that society as a whole supports and values women’s contributions in science. I also believe that a fulfilling professional life can coexist with a meaningful personal life. In the future, I hope to build both a career and a family. While balancing these responsibilities can be challenging, I believe it is possible with determination, organization, and support.

For me, mathematics remains more than a discipline, it is a way of thinking, a source of inspiration, and a path toward understanding the world while appreciating its beauty, much like flowers.

Poetry as Lens: Two Historical Women Mathematicians

Poetry as Lens: Two Historical Women Mathematicians

by Jessy Randall

In 2015, I attended a talk on Sarah Frances Whiting given by Colorado College physics professor Barbara Whitten. Whiting was part of a group of women who cataloged stars at Harvard University in the late 19th century. I sat in the audience scribbling notes about these amazing women – I always listen better with a pen in my hand – and got particularly interested when Whitten showed a slide of a murky blob, an example of the star photographs these women used in their work. To my eyes, it looked like nothing much. Really just a smear.

After the talk, I looked up additional information. (Did I mention I’m a librarian?) I learned that one of Whiting’s colleagues, Annie Jump Cannon, cataloged hundreds of thousands of stars and, years later, could still recognize and identify the blurry photos she’d used doing that work. I pictured her being shown a blobby shape and saying “Oh, yes, that’s good old XZ437583, I remember that one.” Or “Hello, PQ2843b!” I started writing poems about Cannon, persona poems written from what I imagined to be her point of view. 

Annie Jump Cannon (1863-1941)
(first appeared in Asimov’s)
 
1. Annie Jump Cannon Cataloged Stars
 
Annie Jump Cannon
cataloged stars.
 
The work was tedious.
The pay was terrible.
 
But every day for forty years
she went to work
and held the universe together.
 
2. Annie Jump Cannon Goes Home from the Lab
 
She can’t stop seeing them:
the photographs,
black and white smears of stars.
 
They look like throwaways.
They look like nothing.
But not to her, to her they’re clear
 
as alphabets, because 
she’s good at what she does.

Her name led to others, and I found myself spending my lunch hour in the science section of the Colorado College library stacks. Soon my desk was piled high with thick books about historical women in STEM fields. There were SO MANY MORE women scientists and mathematicians than I ever knew. Than I ever dreamed! I wrote a lot more poems. 

Around this time, some powerful men bragged that with enough fame and power, they could get away with anything, including sexual assault. This made me really mad. So mad that I decided to do something about it! But as a librarian and a poet, what could I do, exactly? Well, I wrote a collection of poems about historical women in STEM fields. Maybe not the most effective form of resistance, but the project staved off my feelings of helplessness and hopelessness. 

I got particularly attached to a set of “biobibliographic source books” edited by Louise S. Grinstein,* and went through them page-by-page looking for women to write about. Frequently, some detail of the lives or work of these women leapt out as a perfect metaphor. When I read the entry on Soviet mathematician Nina Bari, the phrase “mathematics for ladies” led to this poem:

Nina Karlovna Bari (1901-1961)
(first appeared in Strange Horizons)
 
After the revolution, she passed the boys’ exam 
and became the first woman in the Luzitania,
students of Nikolai Luzin known for 
their interest in a new kind of math,
 
descriptive math, something more like 
philosophy, sometimes described as
mathematics for ladies.
 
This particular lady worked on functions
converging “almost everywhere”
(a precise term in trigonemetricheskii)
 
and she herself converged almost everywhere, too:
Paris, France; Lvov, Poland; Bologna, Italy;
even a mountain pass named for her lover, Nemytski,
whom she later married.
 
She married Nemytski, but some say her real love
was Luzin. They say she was despondent at his death,
and that when she was not yet sixty (in other words, 59), 
she threw herself in front of a Moscow Metro train.
 
There’s no way to know. It could have been an accident.
But when a woman had made her name calculating 
functions that converge almost everywhere,
we have to think she knew what she was doing.

In the 1920s in the Soviet Union, “mathematics for ladies” (математика для дам / matematika dlya dam) was a derogatory term for descriptive mathematics such as function theory. As in English, the word for “ladies” in Russian has a different connotation than the word for “women” – ladies (дам / dam) being more fancy and posh, not the Soviet ideal of real-world working women (женщины / zhenshchiny). 

I found this idea pretty hilarious. A special kind of math just for women? Different math for different genders? Aren’t numbers the same for everyone? Numbers and formulas and equations don’t change depending on your gender. But then I remembered those statistics about the gender pay gap – that for every dollar a man makes, women make 84 cents, or 90 cents, or 66 cents, depending whom you ask. 

In Bari’s time, math was supposed to be for practical purposes: engineering, architecture, and so on. “Mathematics for ladies” wasn’t real math – real mathematicians considered it to be useless, more like philosophy than math. Much has changed in the past hundred years. Abstract math, or pure math, is now standard in college and university math programs, and pure math scholars receive as much respect as their comrades in applied math (if, perhaps, not always as much funding).

I had a great interest in mathematics right from my childhood. The beauty of mathematical problems and its solutions always captivated me. The logical approach followed towards solving a mathematical problem, the exactness and preciseness of its solutions, was always a source of great fascination. As a school student, I was always in the quest of a solution to the mathematical problems given by my mathematics teacher, in the classroom. During my student life in school and college, I was always ready to tackle that mathematical problem for a solution. 

While growing up, my mathematics teachers in my school and my college were my role models. But I didn’t always have a good mathematics teacher in the school. Some teachers, although quite knowledgeable, could not explain mathematics in a simple language. In the pre-Internet and Communication Technology (ICT) era, those were the times of great struggle, as a student. Access to good quality study materials in mathematics was limited to teachers, in those times. Despite having very limited good quality educational resources in mathematics, I have tried to persevere as a student, professional and a researcher. Mathematics has always been a labor of love for me.

Despite having very limited good quality educational resources in mathematics, I have tried to persevere as a student, professional and a researcher. Mathematics has always been a labor of love for me.

After studying Mathematical Statistics in India and completing my PhD in Germany, I returned to Nepal, where I have worked now in the Department of Mathematics at Kathmandu University for more than 25 years.  In this university, I have delivered lectures on several courses of Statistics and Mathematics at the undergraduate, graduate and postgraduate levels. My main objective has been to popularize these courses among my students. To achieve this, I have always tried to simplify formulas and make them engaging for the students. I have also offered crash courses in advanced levels of Statistics and Data Analysis to interested students and researchers. I have also focused on the interdisciplinary applications of the subject. I have taught students from many disciplines including medicine, engineering, environmental sciences and social sciences. My main aim has always been to promote data-based interdisciplinary studies. This was done by making mathematics interesting and popular among my students.

My main aim has always been to promote data-based interdisciplinary studies. This was done by making mathematics interesting and popular among my students.

I faced some challenges while starting my career as a professional like all my male counterparts. This was due to the switch over from student life to the life of a professional. I experienced at that time that the atmosphere in the classroom as a student was completely different from the atmosphere in the university as a lecturer. In due course of time, I married and had two children. In the initial years of my marriage and motherhood, balancing my married life and my motherhood with my professional life was the source of a great challenge. At that time, due to a Gender Gap in the professional fields of Nepal, I had to figure out how to balance my life. There were no female peers in this field, who could guide me through this part of my life journey. At that time, female professionals were much less in number than male counterparts. My family supported me during this time. I left my daughter with my parents, during my PhD study. 

In the initial years of my marriage and motherhood, balancing my married life and my motherhood with my professional life was the source of a great challenge. [..] There were no female peers in this field, who could guide me through this part of my life journey.

I have to state that there is a Gender Gap in STEM education. STEM subjects seem to be less popular among girls. I feel that girls can break the glass ceiling through their hard work and perseverance in Mathematics and its allied subjects. A sound training in mathematics and its allied subjects prepares them to look at a problem from a different perspective. Girls with enhanced skills in mathematical problem solving are more evidence based and thorough. Mathematics is said to be the language of nature. Thus, these skills have immense scope of interdisciplinary applications. 

With Internet and communication technology, girls of Nepal can be as good as their counterparts in the developed country. By using this technology, girls of Nepal can enhance their skills of problem solving, using mathematics. They should be encouraged to participate in Mathematical events, as this will expose them to the importance of mathematics and the role of ICT in enhancing their skills in mathematics.

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.
