Research interests

My research is focused on stochastic analysis and partial differential equations (PDEs). More specifically, I am interested in stochastic PDEs (SPDEs), diffusion/jump-diffusion processes and their connections to PDEs/integro-PDEs, rough differential equations, and applications. I study both qualitative properties of the aforementioned equations such as existence, uniqueness, regularity, and ergodic properties of the solutions but also their numerical approximation. The last few years I mainly work on (i) regularisation by noise phenomena and (ii) degenerate non-linear SPDEs.
