**Thu**starting at**2pm**in**A1.01****seminar: Algorithms & Computationally Intensive Inference**is a weekly informal reading/discussion

**Fri 2pm**in**D1.07**

#### For Students

- In 2013/4 I am
**teaching ST202**and**ST329** - letters of recommendation
- book a slot for your 2013-4
**END****of term 2 meeting**

#### Research Interests

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