Bayesian inference on biopolymer models. Computational Methods for Complex Stochastic Systems: Sequential Monte Carlo methods can be efficient for analysing state-space models where parameters are known, and the idea is these are used to generate a proposal distribution for the path of the state within an MCMC algorithm.

It is possible to obtain good independence proposals for more general state-models, but this can become challenging, particularly for high-dimensional states and models with strong non-linearities.

Detection of undocumented changepoints: He is one a researcher in computational statisticsin particular Sequential Monte Carlo methods. These experiments involve a series of stimuli being applied to a motor unit, with whether or not the motor unit fires for each stimulus being recorded. This means that the Bayesian fraction of missing information is increasing, and thus the MCMC algorithm mixes more poorly. Paul Fearnhead [ ctb, ths], Jamie Lee [ ctr].

This leads to the idea of updating the state at more than one time-point in a single move; which are called block updates.
