I am an Assistant Professor in the Department of Computer Science at the University of Toronto. I am part of the Theory Group, and work on theoretical foundations of artificial intelligence. I am also a Faculty Affiliate of the Vector Institute for Artificial Intelligence and the Schwartz Reisman Institute for Technology and Society.

I work on problems at the intersection of computer science and economics, such as deciding how to aggregate individual preferences to make collective decisions (social choice theory), learning how self-interested agents behave in a system (game theory), and designing systems that perform well in the presence of self-interested agents (mechanism design). My recent work focuses on building theoretical foundations of algorithmic fairness, and in particular, applying fairness notions developed in the economics literature to algorithmic decision-making.
