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, exploring and extending the capabilities of intelligent decision systems, aiming to ease and assist the human decision making. In particular, my focus is on developing models of computation, algorithms, and intelligent systems designed around our social, psychological, and even economic needs. I have contributed in various areas of computer science such as recommender systems, artificial intelligence, applied machine learning, 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 group recommendation systems which harness such dependencies.

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