I am a Pre-Doctoral Researcher at Google DeepMind, where I work with Dr. Nitish Gupta, Dr. Karthikeyan Shanmugam and, Dr. Prateek Jain. My current research primarily focuses on diffusion models and enhancing the efficiency of large language models.

Before DeepMind, I was a Research Fellow (AI Resident) at Microsoft Research Lab - India with Dr. Manik Varma. My work focused on developing large-scale machine learning models that are parameter-efficient and capable of generalizing to new classes and out-of-distribution data.

Keywords: Efficiency in Large Language Models, Generative Modeling, Large-Scale Machine Learning, Information Retrieval

I graduated with a B.Tech. in Computer Science from Indian Institute of Technology (IIT) Gandhinagar in 2022. For more details about my background, refer to my CV. The best way to contact me is via email.
