About

I'm a postdoctoral research scholar at in the CMB group at Stanford University working in the field of cosmology. Prior to that I did my PhD in Paris at the Laboratoire Astroparticule et Cosmologie (APC). I'm interested in the measurement and scientific exploitation of the cosmic microwave background, especially its faint polarization signal which allows for tests of inflation theories as well as measurements of the physics of large-scale structure formation.

Simons Array

Simons Array is a CMB observatory, scheduled to observe the sky in 2019 with three telescopes in two frequency channels each, located in Chile's Atacama desert. Thanks to its microwave observation in four frequencies, we'll be able to entangle the CMB signal from the constminating emission from our galaxy better than before and set new limits on the tensor-to-scalar ratio, most likely hinting to an inflationary scenario in the early universe, as well as the total mass of neutrinos.
