I have always been passionate about exploring the world of numbers and graphs, finding their intricate patterns and relationships fascinating.

Thanks to my scientific high school education at “Liceo Scientifico Giuseppe Peano”, I was exposed to all the historical and classical branches of mathematics, including Algebra, Geometry, Analysis, and more, with a high degree of knowledge and depth. I was taught important methods for solving equations and performed well in these subjects.

Mathematics was like a game to me: MatheMagics, a sort of puzzle where connecting different pieces represented solving equations, revealing the solutions behind them and the underlying functions.

My Master’s thesis involved developing an epidemiological model to represent a disease in goats.

I pursued Mathematics for both my Bachelor’s and Master’s degrees. My Master’s thesis involved developing an epidemiological model to represent a disease in goats. It was particularly brilliant, receiving two academic recognitions: the Best Master Thesis in Mathematics of the current Academic Year and the Caligara Prize, awarded to Interdisciplinary Master Works with an applied focus. These two awards gave me the ‘wings’ to fly toward the beginning of my academic path.

Therefore, I moved to Switzerland to pursue a Ph.D. in Applied Statistics at the University of Zurich, focusing on the study of Additive Bayesian Networks (ABN) for System Epidemiology. ABN is an innovative methodology that deals with multivariate data, analysing the interconnected and hidden relationships between variables. This marked my first step in transitioning from applied mathematics to statistics.

Mathematics and Statistics are two sides of the same coin, each indispensable and valuable.

Mathematics and Statistics are two sides of the same coin, each indispensable and valuable. On one side, there is the rigour and elegance of formulas, accompanied by foundational knowledge and methodology. On the other side, there is evolution through the modernity of digitalization and concrete applications. Statistics, particularly when applied, is a subject primarily developed using statistical software for data analysis. Additionally, data visualisation is a crucial initial step in comprehending the context. When conducted directly with a tool, it is the outcome of digitalization.

I have always compared my PhD journey to a hike. The peak of the mountain represents the completion of the thesis, or equivalently, the submission and even better, the publication of a scientific paper. I often had the impression that reaching the highest point of the mountain was not possible. This feeling was often demotivating. Overcoming this required strength, determination, and a bit of ambition to finish the task and not give up on the goal. However, the immense satisfaction of completing the PhD ultimately rewarded all the previous effort.

I continued this journey with a PostDoc in Applied Statistics for Nutritional Epidemiology at the International Agency for Research on Cancer (IARC), a part of the World Health Organization (WHO) in Lyon, France. The project focused on studying the relationship between two types of cancer and B-Vitamins intake, involving the development of a Bayesian hierarchical model that accounts for the complexity of the data, including measurement error, disease models, and their intake distribution.

As I began sharing my knowledge, passion, and experiences with them, the joy and gratitude reached their zenith when I observed the students understanding new topics and expressing profound appreciation.

Postdoctoral positions are particularly delicate as they involve a transitional phase in one’s career. At the conclusion of the contract, there may not be a conferred title or a guaranteed position. Therefore, the qualities of strength, determination, and ambition mentioned earlier become even more critical. These attributes are essential for persisting with the research project and not succumbing to challenges, thereby maintaining the original objectives.

After spending a couple of years in France amidst the challenges of academic life, I returned to Switzerland and took on the role of a Scientific Collaborator. This position swiftly evolved into a Senior Lecturer role. Over the course of 6 years, I was affiliated with the University of Geneva, where I taught various courses in Statistics and Mathematics at both the Bachelor and Master levels, delivering lectures in both English and French. Additionally, I served as the Scientific Coordinator of the Master program in Business Analytics.

The first time I embarked on teaching, I felt utterly lost during the preparation phase, a mix of thrill, excitement, and emotion engulfing me afterward. The moment before entering the classroom consistently brought a sense of forgetting my own knowledge, a feeling that dissipated upon seeing the students in front of me. As I began sharing my knowledge, passion, and experiences with them, the joy and gratitude reached their zenith when I observed the students understanding new topics and expressing profound appreciation. These moments stand out as the happiest and most rewarding aspects of my day, constituting a meaningful part of my teaching career.

In this current position, my focus has been on investigating statistical techniques and analyses for demographic studies, particularly on the ageing of the European and Italian population.

During the period in Geneva, my research interests transitioned from biostatistics to philanthropy, exploring specific statistical methodologies highly relevant to that discipline. My shift in research interests expanded further during my role as an Assistant Professor at the University of Florence, a position I held for 10 months just before transitioning to my current role as Assistant Professor with Tenure-Track at the University Ca’ Foscari Venice. In this current position, my focus has been on investigating statistical techniques and analyses for demographic studies, particularly on the ageing of the European and Italian population.

From epidemiology to philanthropy and demography, these are just a few examples of the myriad applications of mathematical and statistical methods. As Galileo Galilei once aptly stated, ‘The Book of Nature is written in the language of Mathematics‘. This encapsulates the secret and magic of this wonderful discipline.

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.

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.

I first fell in love with mathematics in the 3rd grade. It was by pure coincidence though. You see in the 3rd grade I learned how to multiply. Now we did not learn through the tangible way of repeated addition, but with music and memorization. Both of these pedagogical choices stimulated my interest in two ways: my love of music and my competitiveness. Let me elaborate a bit about this.

My whole family is very musical. My maternal grandfather was in a DooWop group named “The Mellows”. He taught my mother to sing, which translated to me singing in the church choir with my siblings. My father constantly played music in our home, especially on his record player. My sister and brother made music a part of their careers and I listen to music any chance I get. Needless to say music played a huge positive role in my life, and still does. So when my teacher played the SchoolHouse Rock multiplication videos for us in class, I was instantly sold! I still sing the song “3 is a magic number” sometimes. I got to see that music could play a large role in learning mathematics. It made mathematics fun and enjoyable. It also helped me memorize the multiplication table because I had memorized the lyrics. This helped with my competitive nature.

Looking at those celebrated in mathematics, I didn’t see someone that looked like me.

I think it is no secret that when learning multiplication, students are often subjected to timed “times table” tests. This was a test or quiz or even just an assignment where you had to fill out a sheet of multiplication problems in maybe around 5 minutes. Oddly, I thrived on this type of competition. It wasn’t a competition with my classmates, but a competition with myself. How many “times-tables” could I remember? How fast could I write them all down? Would I improve my previous score? I think this competitive nature pushed me to love the act of learning, keeping me excited about understanding things at a deeper level. I will also say that this competitive nature has also led to my trivia team, Juneteenth Wreath LLC, being 4 time trivia champs across 2 different platforms #humblebrag.

While this was the first experience I had that created a love of mathematics, I didn’t stay in love. I have walked away from mathematics when I felt that it was not the place for me. Looking at those celebrated in mathematics, I didn’t see someone that looked like me. I assumed that meant that no matter how much I loved math, it did not love me back. (I was a bit of a dramatic teenager.) While I came back to mathematics and made it my career, it wasn’t until recently that I felt like I had a place in mathematics. I would often tell folks “I am a mathematics professor, but I don’t see myself as a mathematician”. The distinction was that while I enjoyed teaching and talking about mathematics, did I think about it on the level that most “mathematicians” do? No. I didn’t enjoy research too much, although I loved working with my collaborators. I didn’t enjoy watching research talks, unless I knew the speaker. I would also be so nervous giving talks, always a bit unsure if I was painting the correct picture. But recently this has all changed.

If today Candice could talk to 3rd grade Candice about this great path through mathematics she is going to venture on, I would tell her about the ups and downs.

I have met so many amazing people who are also mathematicians. Many, but not all, are from minoritized groups in the mathematics community, all forging ahead creating their own definition of what it means to be a mathematician. This community helped me finish my PhD in Mathematics at the University of Iowa, supported me through my postdoctoral work at the United States Military Academy at West Point, and been a great guide through multiple career decisions/milestones I have made/passed, including starting a tenure track position at Smith College and receiving tenure and promotion. If today Candice could talk to 3rd grade Candice about this great path through mathematics she is going to venture on, I would tell her about the ups and downs. Let her know that she is stronger and more clever than she knows. And that she is a mathematician, that she became one that day. I would also give her a small reminder that it is ok to not always be super excited about something– except for music, that is a love that never dies.

I was definitely not one of those scientists who showed exceptional talent from a very young age. As a child I was filled with endless curiosity about everything, but sitting still in front of a desk was not one of my strongest skills. In fact, I was rather bad at school, often arriving late because I had found a frog or wandered off after a hedgehog. I did my very best to study for exams but this did not seem to translate to good grades. I kept trying and by the time I started secondary school I finally got the hang of it. I was warned that when you move from secondary school to high school, and later from high school to university, classes become more difficult but I never really experienced this because I had always had to study for the exams. I had also learned that if I couldn’t solve a problem it just meant that I had to try harder, not that the problem was too hard. I only realised later how lucky I was to have learned proper studying techniques already as a kid.

I like knowing that mathematics has many applications but I have always been mostly interested in the theoretical parts and loved the pureness of mathematics.

I never had anything against mathematics (other than mental arithmetic which I’m still very bad at) but I only really got interested in it at high school. At high school maths problems are like puzzles you have to solve using given rules and tricks. In university the emphasis changed and the weight was more on understanding where those rules and tricks come from and why they are true. I like knowing that mathematics has many applications but I have always been mostly interested in the theoretical parts and loved the pureness of mathematics. It is the only field where questions have indisputably correct answers and where the trueness of a statement can properly be proved.

I have to admit that I didn’t really think too much about what I would do after I got my Master’s degree. Throughout my studies I was told that there was a shortage of skilled mathematicians at the job market but there seemed to be a big gap between what I had learned at the university and what was needed in the real world. Thankfully, my Master’s degree advisor suggested that I should apply for one of the open PhD positions in the Inverse Problems group at the University of Helsinki, where I was doing my Master’s degree.

Starting the PhD was the biggest shock in my studies. Even though the exercises at university were much longer and more complicated than the ones at high school, they always had a clear answer, even if I couldn’t find it. But when I started to do research, I had to get used to the idea that no one knew the answers to many problems I encountered or even if they could be solved. Also, instead of following well-structured courses, where I usually had at least some idea on what was going on, I was now attending several seminars about topics I had hardly even heard of. I was feeling really uncertain about my skills and progress. I was told by several more senior members of my research group that they also used to feel like that and it would get better, but this was only somewhat reassuring. I think the key point they forgot to make was that you won’t stop feeling uncertain because one day you learn to understand all those talks, but because you just get used to the idea that there are so many research topics that you can’t possibly understand them all.

I really like showing people how mathematics is so much more than just the arithmetic they learned to hate at school.

During my PhD I was part of a great research group with supporting advisors and I really enjoyed working at the university. I decided quite early on that I wanted to stay in academia and so after I finished my PhD I moved to the UK for a postdoc position, first in Warwick and then in Cambridge. As a postdoc I had to learn to work even more independently than as a PhD student and how to combat the ever-present imposter syndrome. I also started to do some outreach, giving talks to the general public and school students. I really like showing people how mathematics is so much more than just the arithmetic they learned to hate at school. Nowadays I work as an assistant professor at Delft University of Technology. My current job is a nice blend of research and teaching, and it also offers me possibilities to do outreach. I’m happy if seeing a woman mathematician, who is excited about the subject, makes some little girl consider a science career as a real possibility.
