About

I am a Master's student in Computer Science at Dartmouth College, supervised by Prof. Soroush Vosoughi. I am also a research assistant in the Department of Electrical and Computer Engineering at Carnegie Mellon University, supervised by Prof. Andrea Zanette. Before that, I received my B.Eng. in Software Engineering from Sun Yat-sen University.

My research focuses on diffusion language models, latent reasoning, LLM agents and multi-agent systems, and reinforcement learning.

I am looking for a PhD position starting in Fall 2027.
