About

I'm a Simons Center Independent Postdoctoral Fellow at New York University. My current research interests include world models, mechanistic interpretability, privacy in generative models, and physics of generative models.

Previously, I completed my Ph.D. in Physics at the Tata Institute of Fundamental Research, Hyderabad, where my work on activity-induced transitions in amorphous solids was published in Nature Physics. I was awarded the 2025 Ramakrishna Cowsik Medal for this work.
