I work in the intersection of high-energy nuclear and particle physics.

My main research activity deals with the understanding of how QCD jets interact with the hot and dense medium created in heavy-ion collisions.  I am also interested in non-equilibrium properties of strongly interacting systems, and how to use tools of machine learning and data-driven methods to help us analyze data.

In 2018 I was awarded a TMS Starting Grant to establish a research group at the Department of Physics and Technology.
