Main Research Fields

Galaxy clusters are potentially the most powerful tool to do cosmology, however their progress in determining the cosmological parameters, is not in an advance stage compared to other current cosmological probes (e.g CMB, SNe, BAO). One reason being is that galaxy clusters are highly sensitive to systematics, baryons and feedback. My main research interest is on cluster cosmology but I am also interested in understanding the galaxy group and cluster populations as well as their mass distributions.
