Di Qiu

I am a fourth year PhD student at The Chinese University of Hong Kong, where I am working on geometric modelling, computer vision and computational photography. This fall I will be working as a (virtual) intern at Google Research.

Prviously I worked as an research intern at SenseTime Research, working on applications of deep learning in computational photography with depth sensing devices and physically accurate synthetic data.
