I'm a Research Fellow at Gonville & Caius College, Cambridge (this is a sort of postdoc position).

Previously I was a PhD student at at the University of Cambridge, during which I was a member of St. John's College. I was supervised by Julius Ross. Before that, I was an undergraduate of Trinity College Dublin. I also spent six months of 2016 at the Université libre de Bruxelles, visiting Joel Fine's group (funded by a Fondation Wiener - Anspach scholarship).

My first name is pronounced "Rui" (the "dh" is silent, it's Irish).

I am interested in complex geometry, algebraic geometry and especially the interactions between the two. More precisely, I am interested in the existence of certain canonical Kähler metrics (e.g. Kähler-Einstein and extremal) and notions of algebro-geometric stability (e.g. K-stability). The link between the two is the so-called "Yau-Tian-Donaldson" conjecture, which motivates my work.
