Jérémy Thibault

I am now a postdoctoral researcher at EPFL, working with Clément Pit-Claudel. I am developing a theory and tools for trustworthy low-level patching of critical systems.

I used to be a PhD student in the Formally Verified Security group at the Max Planck Institute for Security and Privacy, supervised by Cătălin Hriţcu, and before that I used to work in the Prosecco team at Inria Paris.

My PhD work lies at the intersection of programming language theory, formal methods, and computer security: using techniques from these fields, I built formally secure compilers, i.e. compilers that are proved to preserve security properties. In particular, I was designing proof techniques for secure compilation that (1) may be implemented in a proof assistant; and (2) scale up to compilers for realistic languages. As the most recent example, we built SECOMP, an extension of CompCert that compiles compartmentalized C code.
