Ph.D., HKUST 2011
Email: 
Welcome to my homepage. I'm currently a Senior GPU Architect working for the Graphics Architecture group at NVIDIA Corporation. Before joining NVIDIA, I was a Senior (Graphics) Research Scientist at Bosch Research (Palo Alto, CA). I obtained my Ph.D. in 2011 from The Hong Kong University of Science and Technology (HKUST, Dept. CSE), advised by Prof. Pedro V. Sander. My thesis focuses on efficient image-space data reuse techniques for rendering and image processing. Previously I have also studied in Xidian University (2000-2004) and Tsinghua University (2004-2007), and have spent most of my early life in my hometown Xi'an, China. This website contains a somewhat up-to-date collection of my work, along with some other related information.

Western classical music always fascinates me. I love listening to and studying the masterpieces of almost all genres. Besides the heart-touching experiences, it is always fun and rewarding to make even a tiny discovery in a beautiful work. Towards deeper understanding, I still need to grab more systematic knowledge on harmonics, music form and other important music theories.
I have been learning to play the violin for more than 10 years. It is such a great instrument that I plan to spend my whole life to master the virtuosity. I had also been a member of Tsinghua University Symphony Orchestra (TUSO) from 2004 to 2007. During the period, we rehearsed more than 20 masterworks and gave many concerts inside and outside the university.
