Announcements

Please attend to CaCos, a sattelite workshop of ISSAC, dedicated to categorical science and proof assistant developments, and what they could bring to computer algebra. (Grenoble, the 26th of July.)

Research

I supervised the PhD of Thomas Braibant: we developped Coq tools that should make it possible, at some point, to study and certify distributed systems (see our the PiCoq project). We released a reflexive tactic for deciding Kleene algebras; the current state of the corresponding library (ATBR) can be found there. we pursued this work by implementing tools for rewriting modulo AC

I also recently played with linear logic, thanks to the CHoCo band members.

I did a post-doc at UPenn, with Benjamin C. Pierce and Aaron Bohannon.

I did my PhD under the supervision of Daniel Hirschkoff, in the Plume team. Here is my dissertation (in french). It deals with up-to techniques for bisimulations in the context of distributed and mobile langages (CCS, pi, kells, join...),
