I am currently on the Llama team at Meta Gen AI. I completed my PhD in the NLP Group at the University of Washington, where I was advised by Hannaneh Hajishirzi and Luke Zettlemoyer. I also have an MS in Language Technologies from Carnegie Mellon University and a Bachelors in Computer Science and Engineering from IIT Kharagpur.

My primary research lies at the intersection of natural language processing and machine learning. I am broadly interested in interpretability, complex interactions, and robust inference for large language models (LLMs) and other foundation models. My research has focused on the following key areas:

  • Explainable AI and model interpretability: Evaluation and training methods for pretrained models to provide faithful, yet readable explanations for their decisions [1][2].
  • Model robustness: Robustness to counterfactual inputs [3], identifying error-prone data sub-populations for distributional robustness [4], addressing factual inconsistencies in LLM generations.
  • Complex interaction and reasoning with LLMs: Interacting with tools (APIs, search engines, code) and humans to plan and realize multi-step reasoning[5]
