I am a reader in the Statistics Laboratory at the University of Cambridge. I am also a fellow of Trinity College. I held the Poincare chair at IHP in the 2015-2016 academic year. Previously, I was a post-doc in the Theory Group at Microsoft Research and at MIT. My research interests are in probability, in particular stochastic interface models (random surfaces and SLE), random walk, mixing times for Markov chains, and interacting particle systems.
