Hi, I am a PhD candidate in Physics at the Georgia Institute of Technology, working with Prof. Kurt Wiesenfeld. I am also collaborating with Prof. Jorge Laval in Civil & Environmental Engineering. Recently I have also begun collaborating with Prof. Sujin Babu and Prof. Ramakrishna Ramaswamy on problems in Active matter at IIT Delhi.

I’m working on non-equilibrium statistical mechanics, with a focus on
collective phenomena, scaling theory, and renormalization-group (RG) methods.
My work combines analytic approaches (path integrals, renormalization group) with large-scale simulations to understand emergent behavior in driven many-body systems.

In parallel, through collaborations with transportation engineering groups, I have also
applied these methods to traffic models and real traffic data, where the same tools reveal scaling structure, and signatures of non-equilibrium criticality.
