My research interests lie in improving generalization performance and safety of agile robotic systems under rich sensing
and allowing their fast adaptation in new, potentially out-of-distribution tasks and environments. I am particularly
excited to leverage algorithmic and theoretical tools from machine learning, optimization, optimal control theory, and
3D modeling to tackle robotic tasks including contact-rich manipulation, legged robot navigation, and drone maneuvering in wind.

About Me

I am from Jiangsu, China. As much as I want to use my first name in Chinese, Zhiyi, I find it very difficult to pronounce for non-native speakers.

I enjoy watching and playing soccer, hitting the gym, and traveling/backpacking. I am also an aviation enthusiast and hold a private pilot license (my story in Chinese).
