My math story started with questions, as many other math stories, I suppose. In the early years of high school, math exercises were fun and challenging. I enjoyed solving them, but I never thought I would study math as a career years later. By that time, I wanted to become an engineer, like my dad, and hopefully work at a hydroelectric power plant. But somehow, math was like gravity, and I felt more and more drawn to it. Hence, I decided to study math at Escuela Politécnica Nacional in Ecuador at the end of high school. Looking back on it, I think I was lucky. Pursuing a career in math was not common in Ecuador. I had the support of my parents and I also was encouraged by my math teacher. However, I had no idea of what math was really about.

I enjoyed the vitality of the formal math language, which brings the possibility to precisely describe a deduction process and articulate a definition from an intuitive notion.

I found the early stages of my undergraduate studies challenging and, sometimes, difficult. However, I was amazed and triggered. I enjoyed the vitality of the formal math language, which brings the possibility to precisely describe a deduction process and articulate a definition from an intuitive notion. The beauty of the simplicity and richness of math made me stay. Nevertheless, the inflection point in my math story happened when I started to work as a research assistant in a project at the Research Center for Mathematical Modeling in Ecuador, ModeMat. In this project, I worked on the numerical solution of visco-plastic fluids. These fluids have a dual behavior; they move like a solid or like liquid depending on the stress imposed on them. I found the mathematical formulation of these fluids fantastic. In this process, I learned the fundamental laws underlying fluid dynamics, optimization methods and I improved my coding skills. This was the starting point of a journey that led me through a Master’s program in Mathematical Optimization and then, like the flow of a Newtonian fluid, to the Ph.D. program in Applied Mathematics. Being part of the Research Center, ModeMat, has shaped part of my life. I have grown up there from an undergrad student to a Ph.D. student under the supervision of four great advisers: Pedro, Sergio, Juan Carlos, and Luis Miguel. Their guidance during the Ph.D. has been essential and valuable. 

I am confident things are changing. At the moment, in my Ph.D. program, we are more women than men.

Nonetheless, I have realized that every time I was part of an international conference, unconsciously I ended up choosing a woman from the Academy as a role model. This unaware action, years later, made me realize how important visibility is. There were few academic women at the math department while I was an undergrad student; therefore, I had the chance to only have one math woman professor. I am confident things are changing. At the moment, in my Ph.D. program, we are more women than men.

I am in the last year of the Ph.D. This journey has not been like the stream of a calm river. Like a visco-plastic fluid, sometimes I have moved like a solid, slowly and without any change in my progress and, sometimes, one just flows like a liquid in a stream of exquisite results. The chance to write about my story came in an opaque moment of uncertainty and lack of confidence. It took me a while to sit and write it down. However, I have genuinely enjoyed it. This retrospective exercise helped me to reconcile and reconnect. Right now, I am focused on this last year of the Ph.D. and interested in a Postdoc. My thesis is still related to visco-plastic fluids. Therefore, in some sense, I think I kind of accomplished my teenage dream. I am not working at a power plant driven by water but I have a better understanding of the fluid dynamics laws to comprehend the power of water. Finally, I would like to take the final words of Natasha Karp’s math story (which I enjoyed a lot reading) as advice: “Enjoy your journey but don’t expect to know exactly where you are going and keep growing and challenging yourself’’. I think that’s what I will do.

As a child, I did not dream of being a mathematician or a scientist; there was a total absence of that role model in my environment. My parents worked very hard so that my brothers and I could attend university. We would be the first generation to obtain a Bachelor’s degree. Living in the countryside and being surrounded by animals shaped me to study agronomy or veterinary medicine. However, my ability in mathematics motivated me to explore a career more related to numbers and abstract thinking.

Since I was a primary school kid, I have enjoyed math homework. I liked to think and invent my own problems. In high school, I was more interested in verbal math problems. I liked the process of “translating” these problems into equations. Despite my taste for mathematics, it was not until my last year of high school that I discovered a career opportunity in mathematics while reading the academic offer of a university. I did not know anyone who studied that subject or that there were jobs for mathematicians. My naive idea was that surely a mathematician knows everything about mathematics, and that caught my attention. One of the first options I considered was studying math to be a good math teacher. During my last year of high school I liked teaching math to my classmates. I was motivated by the idea of transmitting knowledge and helping others to look at problems more naturally.

Everything made sense and brought me back to what I enjoyed as a child: real-life problems translated into equations.

Once I enrolled in university, studying mathematics to be a teacher no longer seemed like a good idea. I realized that high school teachers study pedagogy and that was far from my personal interests. After exploring other options within the same university, I hesitated between chemical engineering and mathematical engineering; both attracted me a lot. The chemistry degree had a high component of physics, and I did not like it enough to study it for so long. I decided to follow mathematical engineering, even with many doubts about its usefulness. It was a kind of blind confidence that I would enjoy it very much.

University was challenging; it was a world that I mostly traveled blindly. The most abstract courses were meaningless to me because although they were fascinating and beautiful on their own, I did not know how they could be used in work life. It was only at the end of my studies that everything became a little clearer. When I did my undergraduate thesis, I connected the theory that I had studied with the world of applications. I understood why we need to seek solutions, guarantee their existence, and analyze their regularity. Everything made sense and brought me back to what I enjoyed as a child: real-life problems translated into equations.

I always had a particular interest in photography, but discovering the physical and mathematical models behind acquisition, reconstruction, and post-processing was something I did not want to stop learning about.

I worked on my undergraduate thesis with Juan Carlos De los Reyes, whom I thank for introducing me to the world of images. I always had a particular interest in photography, but discovering the physical and mathematical models behind acquisition, reconstruction, and post-processing was something I did not want to stop learning about. Since I had just found my passion, I opted for a Ph.D. program to learn more about it. I leaned towards the area of inverse problems, and in particular the modeling and reconstruction of images related to biomedicine. I most enjoyed simulating and visualizing ideas after writing them down on paper. 

This Ph.D. brought me extraordinary experiences such as visiting new places, meeting collaborators from other countries, having an excellent scientific community, just to mention a few. However, there were also challenges along my way: living away from my family, adapting to a new culture, not speaking in my native language, and dealing with frustrations and insecurities when things did not go as expected.

I wish that more and more women feel empowered to study engineering or science and do not rule it out as an option based on stereotypes.

A year ago, I finished my Ph.D. in mathematical modeling in Chile. After some post-PhD experiences as a research associate at the academy in Ecuador, my native country, I will start a postdoc at Millennium Nucleus for Applied Control and Inverse Problems in Chile this month. Although I enjoy teaching, I am happy for this new position dedicated more exclusively to do research.

As a woman, I have been able to feel equal within my workgroups. I was always the only woman, but that has never made me feel less worth than any of my male peers. I wish that more and more women feel empowered to study engineering or science and do not rule it out as an option based on stereotypes. Fortunately, nowadays, we can meet more women, we can look at them as our role models, and we can be role models for the next generations.
