Hi there! I'm a second-year PhD candidate (Aug. 2024 - ) at School of Computing, NUS, advised by Prof. Lin Shao. I am supported by the President's Graduate Fellowship (PGF).

I obtained my B.Eng. (Sep. 2020 - Jun. 2024) in Robotics 🤖 from Zhejiang University, where I had the privilege of working with Kechun Xu, Prof. Rong Xiong, and Prof. Yue Wang.

My research focuses on robot learning for general-purpose dexterous manipulation 🦾.

I am actively exploring internship opportunities and future academic or industry positions.
