My interest lies in the computational challenges arising in Bayesian statistics and statistical physics. This means that I am mostly developing and analyzing new Markov Chain Monte Carlo (MCMC) algorithms.

At the moment my research has a strong focus on the use of Piecewise Deterministic Markov Processes for Monte Carlo purposes. This discovery opens up an entirely new family of elegant algorithms which can be extremely efficient in challenging settings. Naturally, this discovery also leads to many further open questions. See the project page for an overview.

I am an Associate Editor for the Applied Probability Trust, dealing with the Journal of Applied Probability and Advances in Applied Probability.
