Hello! I am an Assistant Professor of the Department of Computer Science at George Mason University, where I co-lead the George Mason NLP group. I am also affiliated with C4I & Cyber Center, Center for Advancing Human-Machine Partnership, and Institute for Digital InnovAtion at GMU. I received my PhD degree from Department of Computer Science and Engineering at the Ohio State University (OSU) in 2021. I have spent time interning at Microsoft Semantic Machines, Carnegie Mellon University, Microsoft Research, Fujitsu Lab of America, and Tsinghua University. I work in natural language processing (NLP) and artificial intelligence (AI), particularly building natural language interfaces (e.g., question answering and dialogue systems) that can reliably assist humans in knowledge acquisition and task completion. Some specific topics include:

  • Language and code: I am interested in studying the interplay between natural language and programming language, including semantic parsing or general-purpose code generation, program-aid language modeling, NLP for AI4SE/Programming, etc.
  • Human-AI interaction: I explore how machine learning systems can proactively collaborate with and learn from humans during decision making, as demonstrated in the setting of "interactive semantic parsing" (our multi-year effort: ACL'23, ICLR'21, EMNLP'20, EMNLP'19, AAAI'19).
  • Information Intelligence with LLMs: I also study improving information intelligence tasks (e.g., question answering, information extraction) in the age of Large Language Models (LLMs), covering problems such as knowledge grounding, tool augmentation, interpretability, and many others.

:star2: Excited to launch Gentopia-AI, an open-source platform for creating, evaluating, and community-sharing Augmented Language Model (ALM)-based Agents! Check out our teams with researchers and engineers from NC State, UMich/PennState, George Mason, CMU, etc. Stay tuned and join us!
