Allen Institute for AI

I am a Research Scientist at Allen Institute for AI. I work on the Aristo project. My research focuses on Interactive Agents, Machine Reasoning, Scientific Discovery, User-centric ML, and Social Science.

I received my Ph.D. in Computer Science from UC San Diego, advised by Julian McAuley. I was fortunate to receive UCSD CSE Doctoral Award for Excellence in Research (2022), Adobe Research Fellowship (2022), Qualcomm Innovation Fellowship (2020), and led UCSD (Team Bernard) in Amazon Alexa Prize, 2019.

Previously, I spent wonderful summers at Allen Institute for AI, Facebook AI Research, Microsoft Research, and Google AI Research. I worked as a technical editor for The Batch, a weekly newsletter by deeplearning.ai. I also co-authored a best-selling book on NLP with O'Reilly Media.

Research Summary

Machine understanding often suffers from the lack of reasoning with world knowledge, making them less reliable and potentially risky. My research goal is to develop communicative reasoners that can learn, adapt, and reason by interacting with the world and produce effective, explainable, and equitable outcomes.

  • Interactive and Communicative Agents: Grounded communicative agents for sequential decision making to improve engagingness, trust, and ability to achieve goals;
  • Reasoning: Generating faithful natural language proof and explanations, improving outcomes with interactive feedback, controllable fair and interpretable outcomes;
  • User-centric Machine Learning: Mixed-initiative clarifications to estimate uncertainty, acquiring user-specific knowledge and injecting them ante- and post-hoc in NLP models.
