Bio and Research Interests

Before moving to Bern, I was Tenure Track Assistant Professor (RTD/b) in the Mathematics Department at the University of Pisa. Previous to that, I was Griffiths research Assistant Professor in the Math Department at Duke University, where I worked with Jonathan Mattingly and Jianfeng Lu. I obtained my PhD in Theoretical Physics, under the supervision of Jean-Pierre Eckmann, at the University of Geneva, after graduating, in physics, from Imperial College London and ETH Zurich.

I am interested in applied probability theory, more specifically in interacting particle systems for real world applications. I have worked on scaling limits for models of chemical reaction networks, focusing on the relations between their dynamics and their structure. More recently, I have worked on the dynamics of scaling limits of machine learning algorithms seen as interacting particle systems, and on dynamics of fluid models.
