About me

My key area of interest is Mathematical Finance. I also take a general interest in problems at the intersection of Probability Theory, Stochastic Analysis, Stochastic Control and Optimisation. In particular, my research focuses on measure-valued processes, the martingale optimal transport problem, and related questions of how to handle model uncertainty in mathematical finance.

Currently hiring PhD students -- please contact me if you are interested or have any questions.
