I am an Applied Research Scientist at Element AI. Previously I was a postdoctoral fellow at the University of Toronto after having completed my PhD in Computing Science at the University of Alberta.  I am interested in artificial intelligence, particularly in the areas of automated planning, heuristic search, knowledge representation, reinforcement learning, and game-playing agents. See the links to the left for a list of publications.

You can also find me on LinkedIn.
