My research interests are stochastic analysis and mathematical finance with current focus on martingale optimal transport, model-free financial mathematics, pathwise stochastic calculus (for financial applications), rough paths, paracontrolled distributions, regularity structures, Skorokhod embedding problem, stochastic (partial) differential equations.
