About me

I'm a PhD student in the Laboratory for Data Security, at École Polytechnique Fédérale de Lausanne.

I'm interested in information security and cryptographic protocols and my research focuses on multiparty homomorphic encryption schemes and their applications to secure multiparty computation.

I'm co-developing and maintaining Lattigo, a multiparty homomoprhic encryption library in Go.
