I am a Professor in the Depts of Statistics and Computer Science, with interests in Monte Carlo methods, inference from stochastic processes, mathematical population genetics, machine learning for genomics. I am a member of the Warwick Machine Learning group.

Teaching

ST341 Statistical Genetics

ST418 Statistical Genetics with Advanced Topics

ST407 Monte Carlo Methods

I am currently supervising undergraduate and Masters projects via our project modules CS350, ST415, ST421, and ST955. I do not participate in URSS. Sorry I am currently unable to take on any undergraduate projects or internships from applications outside Warwick.
