TwitterHi there! I am a Postdoctoral Fellow at PolyU NLP Group. I obtained my PhD degree from The Hong Kong Polytechnic University, supervised by Prof. Maggie Wenjie Li. During the spring and summer of 2024, I visited the SLED Lab at University of Michigan, where I was so honored to work with Prof. Joyce Chai.
Prior to that, I received my MSc and BEng degrees from the School of Computer Science and Engineering, South China University of Technology. During my graduate studies, I was fortunate to be co-advised by Prof. Min Yang at SIAT, Chinese Academy of Sciences.

Research
My recent research interests mainly involve the following directions:
- Situated & Embodied Intelligence: Investigate human-AI interactions in specific environments or situations, learning from language communications and physical actions (EMNLP-Findings'24).
- Large Language Models (LLMs): Explore LLMs' multi-turn preference learning, mechanisms of safety alignment (arXiv'24), etc.
- Conversational AI: Empower conversational agents with goal-driven proactivity (ACL-Findings'23, TNNLS'23, TOIS'24), role-playing personalization (EMNLP'23), role consistentcy (ACL'24), emotional support (AAAI'24), etc.
😀 We are actively seeking highly motivated PhD/master/undergraduate students for collaborative research, including but not limited to the above topics. Please feel free to reach out to me if you are interested.
