Sidney D’Mello received his Ph.D. in Computer Science from the University of Memphis in 2009.  His research interests include the cognitive and affective sciences, artificial intelligence, human-computer interaction, and the learning sciences.  It focuses on uncovering the incidence, dynamics, and influence of affective and cognitive states (e.g., confusion, boredom, mind wandering, frustration) during complex learning and problem solving, applying computational techniques to model these states in context, and integrating the models in learning environments to adaptively respond to the sensed states.  D'Mello has co-edited five books and has published over 180 journal papers, book chapters, and conference proceedings in these areas.  D’Mello is an associate editor for IEEE Transactions on Affective Computing and IEEE Transactions on Learning Technologies, a senior reviewer for the Journal of Educational Psychology, and serves on the executive board of the International Artificial Intelligence in Education Society and Educational Data Mining Society.  He is an assistant professor in the Departments of Psychology and Computer Science at the University of Notre Dame.
