I am a Research Scientist at Facebook Reality Labs. I received PhD in computer science from Simon Fraser University in 2006. I spent a year from 2006 to 2007 as a Postdoctoral Research Fellow at the University of British Columbia. From 2007 to 2017, I was an Assistant Professor and then a Tenured Associate Professor in the Computer Science Department at Boston College. My research spans human pose, tracking, action understanding, 3D computer vision, egocentric vision and deep learning. I developed the people tracking and object association algorithm for Amazon Go, when I was a Senior Research Scientist at Amazon in 2013-2014. In 2016, I led the Computer Vision Team at AutoX.ai at Silicon Valley working on pure vision based next generation self-driving cars. From 2017 to 2020, I was a Principal Researcher at Microsoft Cloud and AI working on real-time 4D computer vision.

Research Interests

My research interests are in computer vision with the focus on image matching, object detection, tracking, pose and action recognition, self-driving technology and deep learning. Please see my list of publications for more details.
