Research

I am currently a postdoc at University of Maryland and NASA Goddard Space Flight Center in the United States. I study neutron stars and their equation of state. Want to do an internship on the topic? Check out this opportunity. More info on how to apply (US and international students) here.

I did my PhD in France at Laboratoire d'Annecy de Physique Théorique (Université Savoie Mont Blanc/CNRS) and Institut de Planétologie et d'Astrophysique de Grenoble in the Sherpas team. I studied the hypothesis of a population of millisecond pulsars in the Galactic bulge to explain the Fermi GeV excess. I have also worked on primordial black hole dark matter. I graduated in July 2023.

I did a year-long master thesis in Germany at the Karlsruher Institut für Technologie, as part of a double master degree program with the Université Grenoble Alpes. I worked on the Fermi GeV excess and for more details, you can flip through my master thesis manuscript (in English).

Before my master thesis, I had the opportunity to do two short research internships. One of them was in astrochemistry and the other one was in cosmology, for which I wrote a short report of my work (in French with an English abstract).

Don't hesitate to contact me if you want to know more about my research! I am also happy to interact with students and share my experience.

An up-to-date list of my publications can be found in ADS.

Highlights

I am a proud organizer of and speaker at Pint of Science 2023 in Annecy.

I won one of the three best poster prizes at the Roma International Conference on Astroparticle Physics (2022) for my poster Needles in a Galactic haystack.

I contributed to the extraction of the Galactic diffuse MeV spectrum from 16 years of SPI data and this work was highlighted in the INTEGRAL picture of the month of March 2022.
