Short Bio

I am a final-year PhD student of the Department of Computer Science, University of Hong Kong. I joined Graphics Lab of HKU in 2014 and my supervisor is Prof. Wenping Wang. Before that I got my Bachelor's degree from Shandong University in 2014.

Currently I am interested in Sketch-based Modeling, Deep Learning, 3D Vision, Medical Image Processing, and Interface Design.
