I'm currently working on visual information retrieval with Dr. Abhinav Shrivastava. Previously, I worked on building trustworthy LLMs via data attribution with Dr. Prathosh A.P. at IISc Bangalore, and on test-time alignment of LLMs at Purdue with Dr. Berkay Celik. I've also had a chance to work with Dr. Pengtao Xie at UCSD to predict histone signatures of non-coding RNAs. Overall, my current interests lie in the geometry of deep learning.

I graduated in Physics from IIT Delhi (2024) with a bachelor's thesis in computational neuroscience.
