Before joining Google Brain, I was a research scientist at Twitter and a professor at the Computer Science department of Université de Sherbrooke. I also spent two years in the machine learning group at University of Toronto, where I was a postdoctoral fellow under the supervision of Geoffrey Hinton.

Research interests
My research focuses on machine learning, i.e. in the development of algorithms capable of extracting concepts and abstractions from data. I'm particularly interested in deep neural networks, mostly applied in the context of big data and to artificial intelligence problems such as computer vision and natural language processing.
