Research Interests:
I am a mathematician working in the interplay between probability and analysis. I particularly enjoy and appreciate the deeper intrinsic connections among different mathematical areas.
My research interests are within the scope of stochastic analysis, rough path theory and their applications, including (but not restricted to):
 Rough paths, the signature transform
 Stochastic/Rough differential equations, diffusion processes
 Gaussian processes, the Malliavin calculus
 Stochastic analysis on manifolds
