**MCMC for intractable likelihood problems**from the Mathematical Statistics conference in Bedlewo are here.

#### Research Interests

**general:**stochastic simulation, computational statistics, Bayesian statistics**specific:**probabilistic algorithms, MCMC, adaptive MCMC, perfect simulation, analysis of algorithms, exact inference for SDEs, intractable likelihood problems- I also like: applied statistics, algebraic statistics, optimal transport, combinatorics...
