Post Doctorate Fellow (Candidate)

Short biography

I am currently a postdoc at VIP lab, University of Waterloo, ON. I recieved both my M.Sc. and Ph.D in computer sciences at Institut National de la Recherche Scientifique, Montreal, QC, in 2003 and 2005, respectively. I was a postdoc in computer science/computer engineering at University of Miami, FL, University of Ottawa, ON, and Ecole Polytechnique de Montreal, QC, in 2005, 2011, and 2012, respectively. From 2007 to 2010, I filled a key position in a startup company (SPGDATA 3D) as computer vision researcher/Technical Director. I also filled an R&D position in game industry as computer vision scientist between 2012 and 2015.

Research interests

My primary research interests lie in visual scene understanding. I am mainly concerned with solving problems arising in visual perception and action recognition, which are key components in many vision applications such as surveillance, robot guidance, multi-modal image interpretation, remote sensing, and visual field monitoring. I also focus my attention on the processing of optical/sonar images for underwater vision applications. Recently I’ve had a chance to explore many aspects falling at the edges between computer vision, computer graphics, and machine learning, such as performance-based animation, procedural animation, shape descriptors and spectral geometry for shape analysis.
