Currently, I am a Full Professor in the Department of Mathematical Sciences and a Faculty Member of the Center for Nonlinear Analysis at Carnegie Mellon University. Before joining Carnegie Mellon in 2024, I was an Associate Professor (with tenure) in the ORFE Department at Princeton University.

At the moment, I am studying interacting particle systems arising in mathematical finance and mathematical physics using tools from stochastic analysis and PDE. More broadly, my interests include a variety of topics in probability theory and related fields: moving interfaces, probabilistic approaches to PDEs, neural networks, stochastic PDEs, large deviations, random operators, and integrable probability.

Here you can find activities I am involved in, my Postdocs and PhD students, publications and submitted papers, collaborators, and CV.
