I always liked solving puzzles when I was younger. My dad even made me eat my bread in puzzle-fashion: he cut it into 4×3 squares, and I had to eat them with chess knight’s jumps, and make sure I did not get ‘stuck’ while eating my entire slice of bread. In high school, however, I liked many subjects, so the choice for mathematics was not obvious at all. I thought about studying biology, physics or maybe something more related to medical sciences. But in the end, I chose mathematics, as I thought this would leave my options open later on.

(…) I am now investigating the mathematics behind spreading processes on networks. These have very important applications in the spreading of epidemics, but are also applicable to viral messages on social media.

Even though my choice for mathematics was rather random, it turned out to suit me very well. I really enjoyed solving exercises, and I also appreciated the fact that the same piece of mathematics can often be applied in so many different contexts. For example, I am now investigating the mathematics behind spreading processes on networks. These have very important applications in the spreading of epidemics, but are also applicable to viral messages on social media.

Because I liked my studies so much, I decided to stay at the university. I first did 4 years of PhD research. During my PhD research, I found doing research a bit lonely, which made me doubt whether I would like to continue on this path. So after those four years, I still did not really know whether I would keep on working at a university, or whether I would go and work for a company instead. But when I got offered a job at Twente University as a researcher, I decided to take it, and see whether I would like it. And I am happy to say that now that I do not have to do my own PhD research, I can make my work more collaborative, which I enjoy very much.

I really enjoy sharing my passion for mathematics with others who maybe never got to see mathematics as useful or beautiful

What I like about my job is that it is very versatile. I can do research, which is basically like solving my own puzzles. On other days I teach more, and have interaction with students, which is also very motivating. Besides that, I participate in a lot of outreach activities. That means that I go to high schools and primary schools to talk about mathematics, but also to theaters, science festivals and podcasts. I really enjoy sharing my passion for mathematics with others who maybe never got to see mathematics as useful or beautiful. In high school I never knew that there was so much more to mathematics than quadratic equations, so I like to share that with as many people as possible!

For example, I wrote blogs about how mathematics helps to predict who will win the soccer world championship, but also about using mathematical graph theory to find the most influential musician. I think that depending on your specific interests and hobbies, there is always an application of mathematics that will appeal to you! So in my outreach activities, I always try to think about what the specific audience could find interesting, and then I will show them an application of mathematics that involves this. The great thing about mathematics is that it is so broad that it is always possible to do so. Of course, this involves a lot of work from my side, but I keep on learning from this as well, and it is very rewarding.

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.
