I'm a PhD student at Clare College, Cambridge University, co-supervised by Rich Turner at the Machine Learning Group and John Aston at Statslab. My research is broadly into machine learning and computational statistics. Before starting 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. I worked as an actuarial consultant before starting my PhD, and during my PhD I've interned as a Quantitative Researcher at G-Research, and as a Research Scientist at DeepMind.
I'm interested in many areas across machine learning, statistics, probability, 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.
I'll be at ICML 2018 in Stockholm, presenting Structured Evolution with Compact Architectures for Scalable Policy Optimisation.
An ArXiv preprint is available for our paper Antithetic and Monte Carlo Kernel Estimators for Partial Rankings.
We recently arxived an extended version of our ICLR paper Gaussian Process Behaviour in Wide Deep Neural Networks. In this newer version of the paper, we formally show that wide stochastic deep networks converge to Gaussian processes under much milder conditions than in the ICLR version.Gaussian Process Behaviour in Wide Deep Neural Networks
I'm currently giving supervisions for Part IB Statistics, and in previous years have given supervisions on Part IA Groups, Part IA Probability, Part IB Linear Algebra, and Part IB Statistics. I gave examples classes for Part III Bayesian Modelling and Computation in Lent 2017, and run MATLAB introduction sessions for Maths Tripos students.
