About

I am currently an NSERC Postdoctoral Fellow, with a joint appointment at University of Toronto (UofT) and University of Waterloo (UW), working with Professor Allan Borodin (at UofT) and Professor Kate Larson (at UW). I am organizing seminars on Social and Economic Networks. I received my Ph.D. in Computer Science from University of Toronto in 2016. I was fortunate to be advised by Professor Craig Boutilier.

RESEARCH INTERESTS

My research is on designing effective decision-support systems and information systems, aiming to ease and assist the human decision making. By studying human decision making processes in various contexts through both theoretical and empirical analyses, I develop models of computation and information systems designed around our social, informational, and even economic needs. I have contributed in various areas of computer science such as recommender systems, artificial intelligence, computer security, and human-computer interaction. Recently, my focus is on decision making in social and economic networks with two intertwined folds: (i) studying, analyzing, and modelling how individuals make decisions when their preferences depend on their friends’ preferences (ii) designing effective decision-support systems which harness such dependencies.

Research Interest Keywords. Decision-Support Systems, Recommender Systems, Social and Economic Networks, Decision Making, Network Science, Probabilistic Modelling, Artificial Intelligence, Multi-agent Systems, Machine Learning, Social Choice, Human Factors, Human Computation, Computer Security, and Authentication.
