I am a Research Fellow working with Prof. Wilfrid Kendall. We are exploring the use of Dirichet forms to address optimal scaling and other theoretical questions about Markov chain Monte Carlo methods. From April 2017 until September 2018 I was a postdoctoral research assistant at Queen Mary University of London with Prof. John Moriarty, working on simulation of rare events and other applications of MCMC methods to energy related problems. I did my PhD (2013-2017) at Imperial College London with Prof. Aleksandar Mijatović on the topic of variance reduction using control variates obtained by approximately solving the Poisson equation.
