Peking University · CS PhD Candidate

Hongcheng Wang

I am a fourth-year CS PhD candidate at Peking University. My supervisor is Prof. Hao Dong.

My current research interests are organized into two parts:

• Chain-of-thought Generation: I study reinforcement-learning post-training for large models, especially how to stably train <think> to better guide <answer>.
• Human-centered Robot Decision Making: I take a Cognitive Behavioral Theory's perspective to enable robots to understand human cognition (e.g., latent demands and preferences) and behavior (e.g., observable habits and norms), so they can better serve people.
