Postdoc researcher,
Max Planck Institute for Security and Privacy (MPI-SP)
About Me
I obtained my PhD at Saarland University in 2016 under the supervision of Gert Smolka.
From 2016 to 2019, I was a postdoc at the ENS Lyon as part of the ERC CoVeCe Project of Damien Pous.
From 2019 to 2021, I was a postdoc in the STAMP team
at Inria Sophia Antipolis Méditerranée
with an individual young researcher grant from UCA-JEDI
From 2021 to 2023, I worked at the MPI-SP in Bochum.
My research is mainly focused on the formalization of mathematics.
In the past, I have worked mostly in the constructive type theory of the proof assistant Coq,
developing formal machine-checked theories for a variety of topics including metatheory of modal logics, automata theory, set theory, and graph theory.
In the last two years, I have been working on cryptographic proofs in EasyCrypt.
In particular, I contributed to the mechanization of the security proof of Dilithium,
a Round 3 candidate for the NIST post-quantum cryptography project.
I have been working on building a graph library for Coq, which is available here.
