About me

I am a French PhD student in astrophysics and cosmology. I am currently based at the Institut d'Astrophysique Spatiale in Orsay and at the Observatoire de Paris. I am particularly interested in the large scale structure of the Universe, and in its evolution.

My work focus on galaxy clusters and inter-cluster filamentary structures, combining multi-wavelength observations. I study the gas in these structures with the thermal Sunyaev Zel'dovich (tSZ) effect, thanks to Planck satellite data, and I link it to the evolution of the galaxies in these structures, from the distant to the very close Universe. I am also interested in computer science and try to combine it with my cosmology-related works, by using for example Bayesian methods or machine learning algorithms.

I am a close collaborator of the ByoPiC team, an ERC-funded project that aims to detect and characterise the different components of the Cosmic Web.
