Ruadhaí Dervan

I'm a Royal Society University Research Fellow at the University of Cambridge, and a Research Fellow at Gonville & Caius College. I've previously spent time in École Polytechnique, Université libre de Bruxelles and Trinity College Dublin.

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

I research complex geometry. I'm interested in both the algebro-geometric and differential-geometric sides of complex geometry, and am particularly interested in the interplay between algebraic geometry and geometric analysis. Most of my research focuses on the existence of canonical metrics in complex geometry (e.g. Kähler-Einstein, extremal), notions of algebro-geometric stability (e.g. K-stability), and more general aspects of moduli theory and geometric analysis. My work is mostly motivated by the "Yau-Tian-Donaldson" conjecture, which links stability notions to the existence of canonical metrics; see Donaldson's survey for an introduction.

I taught Part III Complex Manifolds in Lent Term 2020 and Lent Term 2019.
