Bio

I am an AI Research Scientist at Meta Codec Avatars Lab, where I work on next-generation digital humans.

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 Codec Avatars Lab, 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, and my bachelor's degree in electrical engineering from University of Stuttgart and Wuhan University.
