I am a french high-energy astrophysicist, currently working at the Observatoire de Paris (LUTH), under a PSL postdoctoral fellowship.

My research are centered on the problem of the origin of cosmic rays.
I am a proud member of the gamma-ray observatory CTA, (currently being built!), and of the H.E.S.S. collaboration.

I was a postdoctoral fellow at the Gran Sasso Science Institute (L’Aquila, Italy) (2018-2020)

I was Lecturer in Astronomy and “Frontiers of Science Fellow” at Columbia University (NYC) (2016-2018)


I am currently teaching at the University of Paris at the undergraduate level.

I have been teaching at all level in various contexts (from science fairs in primary schools, public lectures to PhD supervision), with about 500 hours (2012-2021) at the undergraduate level.
