About me

Hey! I'm Christian, a PostDoc researcher at HPI in the Cybersecurity - Identity Management group. Before that, I completed my PhD at EPFL, in the Security and Privacy Engineering Laboratory.

I'm interested in practical aspects of cryptographic protocols. My recent research focuses on multiparty homomorphic encryption schemes and their applications to secure multiparty computation. I wrote a PhD thesis on the topic.

If you want to know more, here are my CV and my LinkedIn profile.


My most notable project is to co-develop and maintain Lattigo, a multiparty homomorphic encryption library in Go. Lattigo implements the latest generation of homomorphic encryption schemes and their multiparty variants.

I also recently released Helium, an MHE-based secure multiparty computation (MPC) framework. Helium builds on top of Lattigo and provides an interface for running multiparty computation over encrypted data.
