General Information
I am currently an Executive Research Director at SenseTime. I lead a cross-functional R&D team where engineers, scientists, product managers, system integrators work together to create high-impact A.I. products. I received my Ph.D. from Department of Information Systems at The City University of Hong Kong where I studied theories and applications of decision making in large scale social systems using machine learning. Prior to that, I spent a few years at Intel and Ericsson (E///) as a software engineer.
