Joana Campos received a PhD with distinction in September 2017, in Information Systems and Computer Engineering from Instituto Superior Técnico, Universidade de Lisboa, under Prof. Ana Paiva's supervision. Joana's work focused on the cognitive modeling of an agent making decisions in conflict situations. It was also part of her PhD to understand how people behave in social interactions and how that impacts human-computer interaction. For that reason, she employed user-centered design approaches to inform system and model development. During her PhD, she worked as a Research Associate in the EU-funded projects SIREN (Social games for conflict resolution based on natural interaction) and LAW-TRAIN (a virtual interrogation training system for law enforcement units involved in drug-trafficking). In 2017 she was a Lab Associate with Disney Research and started a Postdoc in the same lab. During that year she worked on a conversational AI character. Later, Joana, joined Carnegie Mellon University's Robotics Institute as a postdoctoral fellow in Prof. Jessica Hodgins' Lab. In that project machine learning and computer vision to investigate fine-grained details of people's actions and motions in a social environment to understand how people behave in social contexts and what sequences of actions they apply according to their goals and intentions. After that she joined INESC-ID to work on the FCT project SLICE. Currently, Joana is an Assistant Professor at Instituto Superior Técnico, Universidade de Lisboa. Her research is multidisciplinary and addresses fundamental issues in the frontier of artificial intelligence and human-computer interaction, grounded in the computational modelling of human cognition, emotion and social behaviour. She is particularly interested in understanding people's individual and group behaviour and how that impacts human-agent (virtual or robotic) interaction.
