I am a cryptography researcher at the GRACE team at INRIA in Saclay, France, and a professor at LiX (Ecole Polytechnique de Paris).

I am part of the zero-knowledge project Tout-ZK, a joint initiative with Daniel Augot, which aims to systematically evaluate the real-life performance of various ZK software.

Previously I was a senior cryptographer at Qualcomm France and a post-doc with Benjamin Smith at INRIA (2020–2022), and before that at Chalmers University of Technology in Sweden (2019–2020).

I completed my PhD at Eindhoven University of Technology under Tanja Lange and Daniel J. Bernstein, as a fellow of ECRYPT-NET (Horizon 2020 / Marie Skłodowska-Curie). Thesis: "Selected constructive and destructive approaches to post-quantum cryptography".

MSc (2015) and BSc (2012) in computer science at UFSC, Brazil, supervised by Ricardo Custódio and Daniel Panario.
