Guillaume holds a Ph.D in Astrophysics and Space Technologies from University Paris Diderot, and is currently Associate Professor at the department of Physics of University Paris Diderot, on leave at INRIA since September 2019.

His research interests span modelling and simulation of complex system applied to a wide range of scientific fields including coupling between radiative transfer and stiff chemical reaction in molecular cloud of the interstellar medium, atrial fibrillation, transition to turbulence via spatio-temporal intermittency, and more recently modelling and indexing of large scale  systems applied to software development communities.

At Software Heritage as visiting scientist, Guillaume will work on some of the exciting challenges related to provenance index building  and will contribute thanks to the experience in the building of Antepedia, one of the largest knowledge base of software artifacts.
