Welcome to my website. I am an Associate Professor at TU Wien in the Institute of Analysis and Scientific Computing (ASC). From March 2024 I am honored to be supported by an ERC Starting Grant.

My research interest lies in stochastic analysis: stochastic PDEs, regularity structures, rough paths, regularisation by noise, and numerical aspects of stochastic equations.
