About Me

I am a Tenure-Track Assistant Professor in the Department of Computer and Information Science and Engineering at the University of Florida. My research direction is Natural Language Processing (NLP), Large Language Models (LLM), Machine Learning, and Artificial Intelligence. My research vision is to develop innovative algorithms for Knowledge-aware Language Modeling, to advance LLMs reasoning and planning capabilities, as well as ensure trustworthiness and safety alignment of LLMs.

Prior to joining UF, I earned my PhD in Computer Science from Texas A&M University. I received my Master degree in Statistics from Columbia University, and completed my Bachelor degree in Mathematics and Applied Mathematics, along with a double Bachelor degree in Computer Science at the University of Science and Technology of China (USTC).

I was awarded the Rising Stars in Data Science (30 worldwide) by the University of Chicago and University of California San Diego, and Future Research Leaders in Artificial Intelligence (30 national) by the University of Michigan.

Recruiting CS PhD students and Research Interns: I am looking for PhD students starting from 2026 Spring/Fall, and Research Interns all-year round. If you are interested in NLP/LLM research, please feel free to email me. Here are more details.

Research Interests

My research focuses on Natural Language Processing (NLP) and Large Language Models (LLMs). My research aims to develop innovative algorithms and systems for Knowledge-aware Language Modeling, enriching LLMs with diverse forms of knowledge to advance reasoning and planning abilities of LLMs, as well as ensure trustworthiness and safety alignment of LLMs:

• Knowledge-aware LLMs: extracting and integrating structured knowledge into LLMs for knowledge-intensive NLP tasks

• Reasoning and Planning in LLMs: advancing LLMs in complex logical reasoning, moral reasoning, and strategic planning

• Trustworthiness and Safety Alignment of LLMs: ensuring factuality, truthfulness, trustworthiness, safety alignment of LLMs

• Multi-Modality Learning: designing large multi-modal models for content understanding across language, video, audio modal

• NLP/LLMs + X: integrating NLP models and LLMs into various disciplines, such as science, law, psychology, healthcare etc.
