It started all in 4th grade. After being really bad at mental arithmetic, I started to enjoy mathematics for the very first time when concepts became a bit more complex. When I was 9 years old I decided not only to study but also do a PhD in mathematics. So after finishing the A-level, this was exactly what I did. Of course it was hard and different from the maths they teach in high school but I got to appreciate the pure and perfect way of mathematical proofs. However, it was not before the end of my Bachelor that I learned about the diverse applications of mathematics in Biology and Medicine. I never grew very fond of the theoretical part but just saw it as a tool you need to understand and master in order to apply the theory to real world problems. Even though I always had the dream of doing a PhD in mathematics, doubting my skills and abilities made me question this dream. What finally convinced me to continue research and start a PhD in maths was a very honest talk by a female professor at a meeting of women in maths. By coincidence I found the PhD position in Bilbao (Spain) in computational neuroscience and directly knew that this was my topic. 

The most exciting part of research for me was and is solving a problem. It is like a scavenger hunt: you follow traces, read instructions and do trials, which surprisingly involves a lot of creativity.

With the focus on personalised models for a phenomenon related to migraine, I got the opportunity to learn a lot of different strategies from numerical methods to solve differential equations, to curvature approximations and data processing. I worked with neurologists, physicians and medical doctors and learned a lot about interdisciplinary communication. The most exciting part of research for me was and is solving a problem. It is like a scavenger hunt: you follow traces, read instructions and do trials, which surprisingly involves a lot of creativity. Of course it is not all fun, running the simulation for the umpteenth time and writing papers is never going to be my favourite part.

Right when I started to write my PhD thesis, I fell sick and was all of a sudden experiencing personalised medicine from the patient’s point of view. It totally swept me off my feet because I had to pause my PhD for a while and could not stick to the schedule that I had planned. During this time I got a lot of insights in the diversity of medical treatments and was surprised by the differentiated treatment strategies. However, I also saw the potential for data-based fine tuning in the treatment strategies. After this forced break I focused even more than ever on the things that I really wanted: finish the PhD, see the world and find a job in mathematics with an impact.

The first of these points I tackled as quickly as possible. Even though I enjoyed research I could feel a weight lifting from my shoulders when I finally defended my thesis. The second point, traveling for a year after the PhD had always been a fixed idea in my head but talking to friends and family brought up a lot of doubts: would this look bad in my CV? Would this have a negative impact on my career? Would traveling alone be dangerous? However, after very encouraging conversations with professors and friends who had already travelled alone for a longer time, I just took the leap. I bought the plane tickets and went backpacking from Peru to Patagonia in the very south of Chile and through New Zealand by myself. In the beginning before leaving it was scary but in the end it was one of the best decisions in my life, and I learned so much about different cultures, traditions, people and communication that no book or course could have ever taught me.

After hiking the Patagonian highlands, starting as an applied mathematician in a pharmaceutical company is now my next big adventure.

The question if I want to continue research after obtaining my PhD already haunted me during my PhD studies, but when I got back from my big trip I finally knew the answer. I wanted to use my maths skills to help people in the medical sector. Consequently, I solely searched for maths jobs in pharmaceutics where I have just started as an applied mathematician. Changing from the university to a company opens up a totally new universe which I am still exploring but I am very curious and excited to better understand. So after hiking the Patagonian highlands this is now my next big adventure.

During my studies and my big trip I was very lucky to meet encouraging role models, supportive fellow students and inspiring like-minded people that helped me find my way – thank you all.

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.
