My research interests include:
Markov chain Monte Carlo (MCMC):
theory on convergence and efficiency of MCMC algorithms;
methodology such as pseudo-marginal MCMC and non-reversible MCMC;
application of MCMC, especially in areas such as systems biology, epidemiology, ecology and the environment;
Particle filters and Sequential Monte Carlo, especially their use within MCMC algorithms;
Inference for Markov jump process and diffusion models in systems biology and ecology, in particular developing new bridges for use in particle MCMC algorithms;
More general statistical inference for ecology, epidemiology and the environment.
Pseudo-marginal MCMC opened up inference for SDEs and MJPs to a relatively standard approach using particle filters. Here is a simple explanation of the basics and (partial) review of the literature.
Variational representations of Markov kernels can be powerful tools in the analysis of their behaviour; here is a description of three that I have found useful.
During my PhD I found out a little about - particle filters; here is an introduction to the SIR and ASIR filters - an explanation for beginners.
I am (2019-present) the group lead for the Computational Statistics group and extensions and (2024-) head of curriculum development for the MARS (Mathematics for AI and Real-world Systems) UG programme. Between 2022-23 I was dissertation co-ordinator for the MSc in Statistics. From 2013-2019 I was the Programme Tutor for the MSc in Statistics. From 2007-2013 I was Admissions Tutor for the MSc in Statistics.
