Research

I am interested in cosmology: understanding structure formation, dark matter and dark energy and the intersection with galaxy formation. It is an exciting time to be an observational cosmologist, and my research uses the beautiful imaging from DES and KiDS lensing surveys, spectroscopic data from BOSS and now DESI and CMB information from Advanced ACT. My primary research focus weak gravitational lensing which probes the expansion history and growth of cosmic structures. In particular, I focus on tackling the main systematics in those analyses: estimating photometric redshifts, calibrating the shear of galaxies, modelling galaxies' intrinsic alignments, and the impact of baryonic or AGN feedback on our measurements, ahead of all-sky surveys like Euclid and Rubin Observatory.
