I am an astrophysicist, currently working at the LUTH, Observatoire de Paris.


My research are centered on the problem of the origin of cosmic rays, and on the acceleration of particles up to the highest energies.
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 PRFP/MSCA postdoctoral fellow at the Irène Joliot-Curie Lab (IJCLab, 2022), a PSL postdoctoral fellow at the Observatoire de Paris (2021) and 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.
