Biography

2014 – Current PhD Thesis, École Normale Supérieure de Paris, Crypto Team Under the supervision of David Pointcheval and Hoeteck Wee Zero-Knowledge Proofs for Secure Computation 2013 – 2014 MPRI, University of Paris-Diderot, Paris Specialization in algorithmic and cryptography 2011 – 2014 Engineering school, Télécom ParisTech, Paris Algebra, Cryptography, Algorithmic and Theoretical Computer Science 2008 – 2011 Preparatory class for entrance to Grandes Ecoles, Lycée Buffon, Paris MPSI, MP*

Research Interest

My research interest include theoretical and practical feasibility results for secure multiparty computation, and the design and study of cryptographic primitives, such as zero-knowledge proof systems and indistinguishability obfuscation. I also have a broad (amateur) interest for theoretical computer science in general, including computational complexity, fine-grained complexity, foundations of cryptography, and learning theory.
