About me

me

I am a post-doc at IRIF (Université de Paris) in the PPS pole. In did my PhD at LIP6 (Sorbonne Université) under the supervision of Antoine Genitrini and Frederic Peschanski. My research is focused on the combinatorial aspects of concurrency, random generation, and the semantics of probabilistic programs.

I also like to program a lot, for fun and also as a research activity. I consider it to be a real part of research to provide a clean and usable implementation of the algorithms and ideas we develop; and I dedicate a good part of my time to it.

PhD thesis

I defended my PhD thesis, entitled "Quantitative and algorithmic analysis of concurrent programs", on Wednesday, September 29th in Paris. The most up-to-date version of the manuscript is available here.
