About me

I'm a Ph.D. candidate at Cornell Tech in NYC, advised by Prof. Volodymyr Kuleshov. My research focuses on Diffusion Language Models — faster and more controllable alternatives to traditional LLMs. I am currently on the industry job market.

Previously: IIT Kharagpur (Bachelors, EE major); Google Research - Mountain View.
