I am sitting on the train. The ICE drives from Cologne to Hamburg. In this dark evening. My head is spinning after four days of learning about actuarial subjects in a seminar. I use my time to reflect. Thinking a little about the past, a little more about the future and a lot about this moment right now. I am happy. Grateful.

I like being here and in this moment. I am thankful for my talent for mathematics my mom and dad gave me. Thankful for meeting other people in my life, so I could learn and grow and become the person I am right now. Thankful for all the nice people who believe in me and support me. One of my mottos: you are what you have made of yourself. I will never be finished. This would result in stagnation.

The solution of any mathematical problem seemed so easy and elegant to me when I was young: true or false. Nothing else.

Like a central theme, my interest and my ability in mathematics affect my whole life. I love mathematics! The solution of any mathematical problem seemed so easy and elegant to me when I was young: true or false. Nothing else. I wanted to immerse myself in this subject. It was not easy to continue with this wish in a male-dominated world: unmotivated teachers, incompetent advisors at the job center, traditionally-thinking professors at the technical college. Thus, my central theme evolved in a different direction. One constant in my life stayed: me reflecting on my current situation – Who am I? What have I made of myself?

I grew up in a family where natural sciences and logic discussions were welcome. My parents met at the university, later becoming a math high school teacher and a physicist. In highschool, I have always been interested in math and natural sciences. I once asked my math teacher about the mathematical olympiad but I felt completely left alone by him when he didn’t show much interest and asked me to contact the organizers instead of telling me about it. It was frustrating that the lessons in math neither prepared me for the kind of exercises solved at mathematical olympiads nor showed me the possible career paths in science. The job center employee I talked to did not recommend studying math either. Thus, I chose a different path at first. While preparing for my engineering studies, I worked at a locksmithery. In this men’s world, the break room was decorated with a calendar with “aesthetic” images of women. Some old-established professors at the technical college weren’t pleased about women studying engineering.

Remember: if you love something, you will get great at it. I am grateful for being able to realize what I love. I love mathematics.

Finally – I just couldn’t get enough of math – I switched to studying mathematics at the university and went my way to diploma, PhD, being a mother, a teacher, a developer of final exams in math, to leadership in the climate and sustainability working group. I left the “typical” career path of mathematicians again. And came back to my profession: Now I have developed my skills in actuarial subjects working in insurances. And I will continue looking for new challenges.

Right now, I am sitting on the train. Driving from Cologne to Hamburg. And I am happy living in this moment. Happy with my talent for mathematics. It helps me developing, being curious and following interesting new paths. My path leads me further to being an actuarial consultant. I am sure I will encounter interesting tasks, opportunities and people in my future. And I want to show my beloved children: it is worthwhile to look deep within yourself. Be true to yourself. Find a subject that interests you and follow your ambition. Yes, there will always be drawbacks. Fortunately, the world is not as men-dominated anymore as it has been. Remember: if you love something, you will get great at it. I am grateful for being able to realize what I love. I love mathematics.

I came to applied mathematics slowly, and circuitously – but sometimes that makes for the best stories. When I was young, I fell in love with the complexity of biological processes, and thus I chose to study biology for my BSc. My grandmother was a math teacher and I have fond memories of us playing all sorts of educational math games growing up, which instilled in me a joyful, non-competitive view of math. But I never saw myself as a mathematician, it was just something I enjoyed ‘on the side’.

I sat there in complete astonishment of the beauty and power of math to describe a world that I had realized I had always wanted to see in a mathematical light.

It was only when doing my Master’s, when I took a course focused on using dynamical systems to study the life sciences, that I came to see that mathematics needed to be more than a hobby for me. I sat there in complete astonishment of the beauty and power of math to describe a world that I had realized I had always wanted to see in a mathematical light. And, I felt then, everything clicked. That my love for math and complex systems such as biology were not separate, but actually completely intertwined. It was this realization that led me to do my PhD in mathematics. I performed research modeling interactions of growing tumors with their microenvironment and took classes in a wide range of mathematical subdisciplines. It was very difficult as I knew I had less experience with mathematics than many of my peers, but I also had complementary skills in working on real-world scientific problems, which gave me a unique vantage point to think about the methods I was studying. When I kept my focus on the subject matter, I knew I was where I needed to be. It was one of the hardest, but most rewarding experiences in my life.

I work at the interface of data science and applied mathematics to help address challenging problem sets in national security, and more generally in the computational and data science realms.

Something you come to understand by taking a strong pivot, is that both you and the world have the capacity to honor a new stage in your life and career, especially if you approach the challenge thoughtfully and creatively. I had come to understand that for me, the next stage that I wanted to reach was to expand my applied mathematics capabilities to new domains in addition to the life sciences. And, really, I was ready! Studying the life sciences from a mathematical perspective prepares you to handle a variety of complex data problems. The field is full of extremely noisy data – but data that has, if you chip at it long enough, fascinating patterns and meaning underneath the noise. I now get to do just that as a Research Staff Member at the Center for Computing Sciences, Institute for Defense Analyses (CCS/IDA). I work at the interface of data science and applied mathematics to help address challenging problem sets in national security, and more generally in the computational and data science realms. I’ve used approaches ranging from applied dynamical systems (PDEs and ODEs) to, more recently, unsupervised learning methods employing matrix- and tensor-decomposition frameworks. I also hold an adjunct faculty role in the Laboratory for Systems Medicine at the University of Florida, which allows me to continue to collaborate on projects in mathematical and systems biology.

I wish I had known to take advantage of all [professional societies] have to offer earlier in my career.

What I’ve come to realize is that your unique interests and capabilities, even when they may not fit easily into a clear label, do have a place in this world where they will be valued. My background in mathematical biology has given me a unique perspective on the challenges I face in my current role, both from a mathematical and applied sense. And it makes for some fun intersectional research.

Finally, I’d like to make a quick shout-out to the power of professional societies. I wish I had known to take advantage of all they have to offer earlier in my career. Societies like the American Mathematical Society (AMS), Society for Industrial and Applied Mathematics (SIAM), Association for Women in Mathematics (AWM), and Society for Mathematical Biology (SMB) all provide opportunities to network via conferences and meetings, and to learn more about opportunities in and outside of academia utilizing the skills you learn. You don’t need a minimum degree to join – just an interest to connect with like-minded researchers.

My grandma heavily influenced my love of mathematics – as a child she let me have as many sweets as I could count, so I began school with excellent counting abilities! She was also an avid fan of maths and logic puzzles and would do these with me, as a child she had me working on puzzles aimed at adults. As I went through school, I began to appreciate the reality of maths, how it was so much more than counting and arithmetic and instead more closely related to all these puzzles and problems I had loved solving.

I especially enjoy the way maths can be used to understand so much of the world around us and see it as a brilliant language to describe and understand physical processes.

I don’t recall ever deciding to study maths, it just felt like a given. For me it was such an obvious pathway that it never needed to be stated or chosen. And the more I learnt about maths the more I loved it. I especially enjoy the way maths can be used to understand so much of the world around us and see it as a brilliant language to describe and understand physical processes. For me, one of the most enlightening moments of my career was learning about fluid dynamics at university. I had already learnt a lot about standard mechanics (how forces act to move objects etc), but the idea that we could also understand things like the way the ocean changes and moves in an incredibly detailed and definitive way was incredible!

I finished my undergraduate keen to start ‘doing’ something rather than carrying on learning, and my interests led quite naturally to a job building computer models of the ocean for forecasting weather and climate. I loved the work; it was such a great application of the maths I had enjoyed so much. Sadly though, over time I found that being female in this environment was challenging. Many small but persistent issues grew to become more than just tiresome and got in the way of my love for my job. Little things like women being talked over, or not given as much credit as the men we worked with, and people asking questions of my male colleagues in areas where I was the expert. I then moved teams and went from having an incredibly supportive and encouraging manager, to one where I felt there were notable gender issues, and this coincided with a time where the senior leadership’s approach to gender issues were really in the spotlight, and I didn’t feel supported enough by their actions. Eventually I realised I dreaded going to work, and the time had come that I needed to change things. I looked at other jobs, and decided to leave research altogether, but my love of maths was clearly still influencing my decisions, and I started working as a coordinator for two mathematical research centres. It was the perfect tonic after a difficult time. I refound my love of going to work and the sense of satisfaction from it. I remembered how exciting and interesting maths was. And most importantly I had two incredible managers. They supported and encouraged me, reminding me of my skills and abilities. They asked whether I’d considered doing a PhD, and, while I had often thought about it in an abstract way, their remarks gave me the confidence to seriously consider it.

I quickly realised that while I might not be the ‘average’ student, I was far from old, and that there are so many people who don’t follow the traditional academic pathway.

At 33, feeling like this was a foolhardy thing to begin at such an age, but also super excited about the chance to spend 4 years absorbed in something for the pure interest of it, I began my PhD looking at using machine learning to model the ocean. I quickly realised that while I might not be the ‘average’ student, I was far from old, and that there are so many people who don’t follow the traditional academic pathway. Really, there is no average student. We all come to this with such a different perspective and history, and so many individual advantages and disadvantages. I found (as I’d hoped) that my background meant I have many relevant skills that have made things easier. But also, my fundamental knowledge was rusty, and my brain felt so slow at times when trying to pick up new things. Alongside this, it feels my life is much more complicated now than it was in my early twenties, and a number of difficult things in my personal life have impacted my work, and I’ve really struggled at times. Throughout this though, I try to remind myself of the privilege of being able to sit at my desk and spend my time thinking about something which I still find so incredibly cool – the way we can use this brilliant language of mathematics to understand the world around us.

I’m lucky to have had some incredible people support and inspire me along the way, helping me to get to this point – thank you to them all!
