These days I work at Meta. I am part of the broader Meta Superintelligence Labs (MSL) and I particularly focus on post-training of roleplaying LLMs to improve their capabilities.

I worked as an Applied Scientist at Amazon from 2020-2024. I was in the AGI org primarily working on improving Alexa powered experiences. I worked on a variety of things, some of which include post-training of LLMs, meta-reasoning for enhancing tool calling/reasoning capabilities of LLM, self-learning conversational assistants etc.

Before my stint at Amazon, I obtained a Masters in Language Technologies within the School of Computer Science at Carnegie Mellon University. I worked with Prof. Jamie Callan on Conversational Search. Prior to joining CMU, I was a student at International Institute of Information Technology Hyderabad. I was a Dual Degree Student pursuing a B.Tech in Computer Science and MS by Research in Computational Linguistics. I was a part of the Language Technologies Research Center and was advised by Prof. Vasudeva Varma and co-advised by Dr. Manish Gupta. During that time I worked on various aspects of Computational Journalism. I also worked a bit on translation. During this, I co-founded a startup Ping with three other members.

I have an Erdos Number of 5. While this does not have any signifiance, I simply put it here because it was a cool thing for me in the past.
