About Me ...

Leonid Sigal's Photo

I am an Associate Professor in the Department of Computer Science at the University of British Columbia. I am also an NSERC Canada Research Chair (CRC II) in Computer Vision and Machine Learning and a CIFAR AI Chair at the Vector Institute for AI in Toronto. In addition, I serve as an Academic Advisor to Borealis AI.

Prior to this I was a Senior Research Scientist at Disney Research Pittsburgh and an Adjunct Faculty member at Carnegie Mellon University.

My research focuses on problems of visual understanding and reasoning. This includes object recognition, scene understanding, articulated motion capture, motion modeling, action recognition, motion perception, manifold learning, transfer learning, character and cloth animation and a number of other directions on the intersection of computer vision, machine learning, and computer graphics.
