**I'm currently highlighting the following**

**seminar: Algorithms & Computationally Intensive Inference**is a weekly informal reading/discussion

**Fri 1215-1345**in**C1.06**(Term 1 & 2)**A1.01**(Term 3)**Simulation Reading Group**

#### 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...
