Biography

I am a PhD student at University of Toronto, machine learning group and Vector Institute. I am also a research intern at NVIDIA. My supervisor is Prof. Sanja Fidler. During my undergraduate years at HKUST, I was supervised by Prof. Qifeng Chen and I was fortunate to work with Dr. Li Erran Li, Prof. Alexandre Alahi@EPFL, Dr. Yuwang Wang@MSRA and Prof. Xiaolong Wang@UCSD.

My research interests are in computer vision, particularly generative modeling and 3D vision.
