I am an NCCR SwissMAP fellow at ETH Zürich. Before this, I was a postdoc at the Max Planck Institute in Leipzig in the groups of Benjamin Gess and Felix Otto. I obtained my PhD in Mathematics in June, 2020 from Imperial College London, under the supervision of Greg Pavliotis and José Antonio Carrillo.

My research lies at the intersection of PDEs and probability. I am interested in interacting particle systems, SPDEs, large deviations, optimal transport, random dynamical systems, and some aspects of incompressible fluids (mixing, enhanced dissipation, etc.).
