Assistant professor at IMECC - Unicamp, currently supported by a FAPESP Young Investigator Grant. I am part of IMECC’s Geometry and Topology (GeoTop) research group.
I work in the areas of Number Theory and Algebraic Geometry, mainly on questions involving periods of algebraic varieties and their differential equations, modular forms, transcendence, and algebraicity.
I did my PhD at the LMO - Université Paris-Saclay, under the supervision of Jean-Benoît Bost, and I was a postdoc at the MPIM - Bonn and at the MI - University of Oxford, working with Francis Brown.
