Short Bio

I am a Ph.D. student affiliated to ICON@Columbia and the Columbia Core AI Lab (CAIL), where I am advised by Prof. Zhengbo Zou. From 2021 to 2024, I studied as a PhD student at University of British Columbia. I earned my Master’s degree at Carnegie Mellon University, where I was advised by Prof. Pingbo Tang.

Inspired by Hayao Miyazaki’s films, I build robots that perceive, preserve, and reconstruct the world’s dynamics.

Mentoring

I am always interested in mentoring highly motivated undergraduate and master’s students in CE/ME/CS/EE. If you’re at Columbia and would like to discuss project ideas or research opportunities, don’t hesitate to send me an email!
