Short Bio
I'm currently a senior staff research scientist at Innopeak Technology, OPPO US Research focusing on next-generation mobile AR/VR R&D. My research interests are in the Vision and Graphics related fields. More specifically, neural rendering, image-based rendering and relighting, 2D/3D human body/face modeling and understanding. Before that, I obtained my Ph.D. degree in Computer Science from the University of Delaware, Newark, DE, USA. I worked on 3D non-rigid dynamic human shape reconstruction and completion, dynamic mesh sequences compression, and human semantic segmentation.
Education
Ph.D. Computer Science, University of Delaware, July 2015 - Feb 2019.
M.S. Computer Science, University of Missouri. Jan 2013 - July 2015.
NEWS
Two papers accepted to CVPR 2024 in Seattle.
One paper accepted ACM MM 2023 in Ottawa.
Two papers accepted to ICCV 2023 in Paris.
We are consistently seeking highly motivated Ph.D. interns on various AR/VR topics including but not limit to 2D/3D human body/face modeling and understanding, novel view synthesis, image-based rendering, and relighting. Drop me an email if interested.
