Interests

I'm currently an assistant professor at the Computer Science Department of Instituto Superior Técnico - Technical University of Lisbon (IST-UTL), where I teach courses on Introduction to Programming, Artificial Intelligence, Logic Programing, and Autonomous Agents and Multi-Agent Systems.

I've been working with computational models of emotions and agent architectures since 2004, when I started working on my MsC. By then my main interest was to understand how emotions affect cognitive processes and to build agents that could use such processes to influence behaviour.

In the most recent years, my attention shifted from the influence of emotions in reasoning towards reasoning about emotions and building plans of actions to influence emotions in self in others; the third and fourth skills of Emotional Intelligence as proposed by Mayer and Salovey. I'm particularly interest in studying how Interpersonal Emotion Regulation affects social relations and helps build believable social interations.

Additionally, i'm also studying and "playing a bit with" Theory of Mind, Mindblindness, Memory and other cognitive processes. Actually, if there is something that is cognitive, symbolic, based on psychological studies on human behaviour, and implementable, then I'm interested.
