Joost Broekens (Phd) is assistant professor of Affective Computing at Leiden Institute of Advanced Computer Science (LIACS) of Leiden University, and co-founder and CTO of Interactive Robotics. His research includes computational modeling of emotion (mood, appraisal, applied in games, robots and agents, and theoretical), human-robot interaction and Reinforcement Learning. He is member of the executive board of the Association for the Advancement of Affective Computing (AAAC), associate editor of the Adaptive Behavior journal, and member of the steering committee of the IEEE Affective Computing and Intelligent Interaction Conference. He organized interdisciplinary workshops on topics including computational modelling of emotion (Lorentz, Leiden, 2011), grounding emotion in adaptation (IROS, 2016), and emotion as feedback signals (Lorentz, Leiden, 2016), and edited special issues on these topics (in e.g., Springer LNAI, IEEE Transactions on Affective Computing, and Adaptive Behavior). His research interests include emotions in reinforcement learning, computational models of cognitive appraisal, emotion psychology, emotions in games, human perception and effects of emotions expressed by virtual agents and robots, emotional and affective self-report, and human-robot interaction.
