"Cluster Lensing in the Stage-IV Era"

Charlie Mpetha did his undergraduate at Lancaster University, then moved to a PhD in gravitational wave cosmology at the University of Edinburgh. Mid-way through his PhD, in 2023, he won a Leverhulme Study-Abroad scholarship to work at the WCA for a year with James Taylor on topics in cluster cosmology. Now, Charlie is in his first year as a NASA Postdoctoral Fellow at Goddard, working on cluster science for the Nancy Grace Roman space telescope.
