I am a tenure-track assistant professor in The Hong Kong University of Science and Technology, Department of Computer Science and Engineering. I obtained my PhD from Carnegie Mellon University, Language Technologies Institute in the School of Computer Science in 2022, where I was co-advised by Graham Neubig and Taylor Berg-Kirkpatrick. Before that, I received the bachelor degree in Electronic Engineering from Shanghai Jiao Tong University in 2017. I also spent some time at Facebook AI Research (2019) and Salesforce Research (2020).

Prospective Students:

I am always actively looking for strong and self-motivated students to join us! Current PhD applications are for 2025 Fall, I encourage you to reach out early to ensure consideration. For research assistants/visitors, at this moment I only host external visitors in exceptional cases, for example, if you have a good research background and work on projects that align with my interests well. Please drop me an email if you are interested.

Research

I am generally interested in natural language processing and machine learning. Current interests are on several aspects around large language models:

• parameter-efficient tuning – efficiency, modular, composition
• multi-step reasoning
• factuality – method and evaluation
• evaluation of foundation models – knowledge, reasoning, tool use, etc.
• data-centric approaches
• language model as agent
