I am an assistant professor at the Department of Mathematics at Northeastern University, working on probability theory in discrete systems and statistical physics. I am broadly interested in discrete systems that undergo phase transition phenomena.

My research has two main focus areas: first, I work on lattice models, such as the Ising model, the random-cluster model, or the loop-O(n) model. More specifically, I have been working on using tools from probability, analysis, and exactly solvable systems to gain insight into the critical behavior of some classical models of statistical physics.

I am also interested in large deviations of subgraph counts in random graphs, studying the localization phenomena associated with the upper tails of these objects.

Before arriving to Boston, I worked as a postdoctoral fellow with Prof. Ron Peled at Tel Aviv University, Prof. Hugo Duminil-Copin at IHES Paris and the University of Geneva, and Prof. Stanislav Smirnov at the University of Geneva. I completed my PhD at the Courant Institute, where I was advised by Prof. Sourav Chaterjee, currently at Stanford University, and Prof. Joel Spencer.
