Biography

I am a fifth-year Ph.D. candidate in the EECS department at the University of California, Berkeley. My advisor is Prof. Yi Ma. Previously, I received my Bachelor’s degree from Yao Class at the Tsinghua University. I am currently funded by Sony Inc. You can download my PGP public key here.

I am interested in 3D vision and computer graphics. My recent research focuses on developing principled methods related to 3D reconstruction. My goal is to obtain high-quality 3D models by incorporating physically sound geometric knowledge into data-driven approaches for recognition and reconstruction.

Research Assistant

Tsinghua University

Advised by Jianyang Zeng, I did research related to the proteins’ 3D structures in the Machine Learning and Computational Biology Group at IIIS when I was a undergraduate. I designed fast and massively parallel combinotorial search algorithms and tested them on the protein design problems. I also implemented a CUDA version of RELION to accelerate the 3D reconstruction of protein structures from cryo-microscopy images, which later turned into my undergraduate thesis.
