About Me

Welcome! I’m a tenured research scientist at Inria Grenoble working with the Privatics team. Previously, I was a postdoctoral researcher in the Comète team at Inria Saclay. I received my Ph.D. in Computer Science from the University Bourgogne Franche-Comté (UBFC) and my M.Sc. in Electrical Engineering from the São Paulo State University (UNESP).

Currently, my research interests are differential privacy and ethical aspects of machine learning (e.g., privacy and fairness issues).
