Research
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.
Research-level tutorials
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.
