I am a senior undergraduate at Peking University working with Prof. Xiaojun Wan. I was an undergraduate visiting researcher (UGVR) at Stanford University, advised by Prof. Diyi Yang.

My research explores how AI systems adapt to (1) tasks, (2) users, and (3) social contexts.

• Task Adaptivity: Improving how LLMs retrieve, select, and structure contextual knowledge for diverse tasks.
• User Adaptivity: Developing interaction mechanisms that allow agents to adapt to evolving user goals and preferences.
• Social Adaptivity: Studying how social factors influence model decisions to build socially aware and fair AI systems.
