About me

After a master degree in Grenoble (Université Grenoble Alpes) in subatomic physics and cosmology, I prepared a thesis in Cosmology at Laboratoire de Physique des 2 Infinis Irène Joliot Curie (IJCLab), under the supervision of Thibaut Louis. During my thesis, I mainly focused on the tension between local and CMB-derived measurements of the expansion rate of the Universe. I have studied the existence of potential instrumental systematic contamination in the best CMB datasets available to date and investigated a promising theoretical solution to the tension called Early Dark Energy (see a list of my publication for more details).

As part of the ACT Power Spectrum working group, I contribute to the analysis of the sixth data release of primary CMB power spectra from data collected by the Atacama Cosmology Telescope (ACT). The aim of this instrument was to measure the small scale CMB polarization anisotropies from the Atacama desert. We have already provided a map of the reconstructed gravitational lensing of CMB photons from ACT DR6 data (2017-2021) which probes the matter density along the line of sight (see here for a CNRS press release I contributed to). The primary ACT DR6 power spectra analysis is still ongoing, and has allowed to strenghten the [PSpipe] data analysis pipeline which will be used to perform the analysis of the Simons Observatory (SO) Large Aperture Telescope data.

As a postdoctoral research assistant at Oxford University, I recently joined the SO-BB working group with the aim of providing a robust power spectrum analysis pipeline to analyse the first data from Simons Observatory Small Aperture Telescopes that are expected to be available during 2024.
