Research

My research interests have been running freely in the fields of algebraic geometry and number theory, with a special focus on the arithmetic of curves, non-archimedean gemetry and moduli spaces. I still like to think about these topics but I have now expanded my interests to include pedagogical aspects, such as how we learn and assimilate mathematical notions and how to convey these notions to a general public through outreach and public engagement.

I also enjoy discovering applications of algebraic geometry to other branches of science. I am a member of the applied algebra and geometry network and I like to learn about computational algebraic geometry, data science, and algebraic statistics.
