I am a postdoc in the working group of Stefan Schröer at Heinrich-Heine Universität Düsseldorf. I received my PhD in March 2022 from IMPA, where I was advised by Karl-Otto Stöhr. Before that, I was an undergraduate student at Universidad Nacional de Ingeniería in Lima, Peru.

I work on algebraic geometry in positive characteristic. I am interested in regular curves that become non-regular after base change, and especially in their connection to fibrations by singular curves in positive characteristic. Among the tools I like to use is the theory of non-conservative function fields.
