Short Bio

I have always wanted to understand the world around me, and the tool I have chosen is applied mathematics.

I did my undergraduate studies at the Universidad Nacional de Córdoba (Argentina), and then went to the University of Maryland (United States) to do my Ph.D. in Applied Mathematics under the supervision of Antoine Mellet.

After my Ph.D., I held postdoctoral positions at UNESCO's ICTP (Italy) under the supervision of Francesco Maggi and Imperial College (United Kingdom) under the supervision of Greg Pavliotis and Jose Carrillo.

My research interests are mostly related to mathematical modelling through Partial Differential Equations (PDEs). For the most part, my work is devoted to understanding self-organization phenomena in systems with a large number of particles/agents. Using this perspective, I am currently trying to understand the dynamics of parameter training in commonly used machine learning algorithms.

Nowadays, my research is being funded by CNPq and Instituto Serrapilheira.
