About me
I am a Research Fellow working with Adam Johansen and Theo Damoulas as part of the Warwick Machine Learning Group, the Department of Statistics at the University of Warwick, and the Alan Turing Institute. I develop tools for machine learning, Bayesian inference, and computational statistics by combining concepts and techniques from optimization and Monte Carlo; see here for a recent example. In the past, I worked on Markov processes, numerical methods for the analysis thereof, and applications of control theory to synthetic biology. I have also been writing a book on Markov chains, see here for the latest draft.
