Abstract: 

Random walks and particle systems are both fundamental objects of study in probability theory, and are the focus of my research interest. They are linked to PDEs, biological growth models and other physical phenomena in a natural way. After briefly introducing my earlier work on random walks on time-dependent graphs, I will focus on recent work with Franco Flandoli where we prove the scaling limit of a system of locally interacting diffusions subject to environmental noise towards a Stochastic PDE of coagulation type, which is motivated by understanding whether turbulence in the atmosphere accelerates rainfall formation or not.
