Bio

I am an AI Research Scientist at Meta working on foundation models for 3D/4D vision and video generation.

I received my Ph.D. degree from ETH Zurich under the supervision of Prof. Otmar Hilliges and Prof. Marc Pollefeys. I was supported by the Microsoft Swiss JRC PhD Fellowship, through which I collaborated closely with Dr. Julien Valentin.

During my Ph.D., I was a research intern at Meta, mentored by Prof. Yaser Sheikh. After my Ph.D., I worked as a Senior Researcher/Postdoc at ETH Zurich for three months.

I received my master's degree in robotics from ETH Zurich with distinction, under the supervision of Prof. Luc Van Gool, and my bachelor's degree in electrical engineering from University of Stuttgart and Wuhan University.
