I am a researcher (chargé de recherche) at CNRS (Centre National de la Recherche Scientifique). I am currently working in observational cosmology at Laboratoire Astroparticule & Cosmologie (APC) in Paris, France.
I am interested in understanding what happened in the first fraction of the first second of our Universe, as well as trying to figure out what is the fundamental nature of dark energy. Over the past decade, I have been focusing on the characterization, modeling and development of mitigation techniques for instrumental and astrophysical systematic effects which are the major limitation factor for current search for primordial gravitational waves. I have also looked at late Universe physics such as the reconstruction/removal of gravitational lensing effects from CMB observations as well as the cross-correlation of CMB data with optical or spectroscopic measurements.
