Hi There, Welcome!

I'm an incoming assistant professor at the Hong Kong University of Science and Technology (HKUST) Computer Science & Engineering (CSE) Department, starting in Fall'24. I am actively recruiting PhD, Masters, and Undergraduate student to join us in exciting NLP/AI research work. If you're interested, please fill out this form, thanks!

At present, I am a Ph.D. candidate at the Blender Lab of UIUC, where I am fortunately advised by Prof. Heng Ji. My research focus centers around socially-situated human-centered trustworthy NLP/AI with multimedia knowledge reasoning capability and scalable alignment principles. In particular, here’s a handful selection of my recent research that dive into the fundamental model architectural mechanisms or frameworks empowering harmless, helpful, and honest information communication:

• Norms Discovery and Explainable Norms Violation Detection: NormSAGE^_[1]; LM debiasing and detoxification^_[2][3]
• Fine-Grained Information Extraction: NewsClaim, a novel benchmark for claim extraction with attribute knowledge^_[4]; RESIN, a state-of-the-art schema-guided cross-document cross-media IE and event tracking system^_[5]
• Misinformation Detection: reasoning across multimedia and background knowledge^_[6]; cross-document misinformation detection ^_[7]; battling fake and biased news^_[8]
• Diverse Human-Centered Pro-Social Reasoning Tasks: SmartBook generation for situation reports^_[9]; Decoding the Silent Majority, for social media response forecasting^_[10]; COVID KG Construction and Drug Report Generation^_[11]
• Intelligent Agent with Tool Learning Capability: CREATOR, LLM tool creation through abstraction reasoning^_[12]; CRAFT, customizing LLMs through specialized toolset creation and retrieval^_[13]
• Foundation Model Hallucination Control and Alignment in Honesty/Faithfulness: R-Tuning, teaching LLMs to refuse uncertain questions^_[14]
