Peng "Richard" Xia (夏鹏)

I am a Ph.D. student at Department of Computer Science, The University of North Carolina at Chapel Hill, advised by Prof. Huaxiu Yao. Before that, I was briefly enrolled (2023-2024) as a Ph.D. student at Monash University, advised by A/Prof. Zongyuan Ge. Formerly, I worked as a research intern at Deep Research Team, Tongyi Lab, Alibaba and Microsoft Research.

My research focuses on scaling agent through mid/post-training and data scaling. I focus on building (M)LLM agents equipped with complex tool interaction and long-term memory, ultimately striving towards autonomous self-evolving systems.
