Research interests

My research interests lie in the field of computational Bayesian inference, with a focus on developing hardware-specialised methods, for example, designing sampling algorithms that explicitly take advantage of the parallelism of modern GPUs rather than implicitly. I have recently taken a liking at statistical handling of diffusion models, which will likely take up a lot of my time in the coming years. Other interests lie in embarrassing (or not) parallelisation of statistical algorithms, statistical efficiency in state-space models, gradient-based MCMC, coupling methodologies, and optimal transport.
