I'm currently a Research Scientist at Uber ATG Toronto. I completed my MSc in Computer Science (Machine Learning Group) at the University of Toronto (2016-2018) and was supervised by Raquel Urtasun. Prior to that I completed my BASc in Mechanical Engineering (Mechatronics Program) at the University of British Columbia (2011-2016). My research interests lie on the intersection of Computer Vision and Machine Learning. My CV is available here.
