Visiting Researcher


I'm currently a Visiting Researcher at Google Toronto. Previously I was a Sessional Lecturer at the University of Toronto, and a Research Scientist at Wayve.

I completed my PhD at the University of Cambridge in Oct. 2018, where I was supervised by Professor Roberto Cipolla, head of the Computer Vision and Robotics group in the Machine Intelligence Lab, and Dr. Antonio Criminisi. My PhD was supported by a Microsoft Research Ph.D. Scholarship and I collaborated with researchers at Microsoft Research Cambridge (UK) extensively.

I am currently interested in deep learning, specifically the effect of structure in learning deep neural networks, and their application to problems in computer vision. I have in the past worked on 3D computer vision, towards methods for processing and recognizing objects in large point clouds.

Outside of research, I've worked on open source projects such as the Linux kernel and the Point Cloud Library (PCL).
