Yifei Sun (孙逸飞)

I am an assistant professor (ZJU-100 Young Professor) at the School of Software Technology at Zhejiang University (ZJU). I received my Ph.D. degree from the College of Computer Science and Technology at Zhejiang University in 2025, under the supervision of Prof. Yang Yang. Since graduating with my PhD, I have been working closely with Prof. Yunjun Gao and his DAILY Group. Previously, I visited National University of Singapore (NUS) from Nov 2023 to Jun 2024. (working with Prof. Bingsheng He, Prof. Bryan Hooi and Prof. Zemin Liu).

My research interests include foundation models for structured data, agentic RL, and whole-body VLA. I have published several papers in top tier venues, with citations on google scholar and on github.

Ongoing Work

Planning and Evolving for Agentic Systems.
Reasoning Models for Relational Data.
Harnessing VLA for Long Horizon tasks.
