About Me
I'm a Research Scientist at DeepMind. I'm interested in many areas across statistics, probability, reinforcement learning, and optimisation, and interactions with areas of pure maths such as group theory and optimal transport theory. To date, I've worked on areas including inference problems for discrete graphical models, Monte Carlo methods (particularly over non-Abelian groups), reinforcement learning, and probabilistic deep learning. Prior to joining DeepMind, I was a PhD student at Clare College, Cambridge University, co-supervised by Rich Turner at the Machine Learning Group and John Aston at Statslab. Before my PhD, I studied for a BA and MMath at Cambridge. I focused mainly on Probability and Algebra courses in the final year, and wrote my Part III essay "Mixing Times of Random Transpositions" under the supervision of Nathanaël Berestycki.

Teaching
During my PhD, I gave supervisions on Part IA Groups, Part IA Probability, Part IB Linear Algebra, and Part IB Statistics. I also gave examples classes for Part III Bayesian Modelling and Computation in Lent 2017, and ran MATLAB introduction sessions for Maths Tripos students.
