I'm a Harrison Early Career Assistant Professor at the Statistics Department at Warwick. My research interests include Monte Carlo methods, statistical inference from stochastic processes and in settings with intractable likelihood, Bayesian nonparametric statistics, coalescent processes, and mathematical population genetics.
In 2018/19 I am teaching ST341/ST418 Statistical Genetics.
