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.
