Yiyi Liao

Zhejiang University

I am an assistant professor in Zhejiang University, leading the X-Dimensional Representations Lab (X-D Lab). Before that, I was a Postdoc in Autonomous Vision Group at the University of Tübingen and the MPI for Intelligent Systems, working with Prof. Andreas Geiger. I received my Ph.D. in Control Science and Engineering from Zhejiang University in June 2018 and the B.S. degree from Xi’an Jiaotong University in 2013.

My research interest lies in 3D computer vision, including scene understanding, 3D reconstruction and 3D generative models.

For prospective students interested in computer vision, feel free to contact me via email!
