Affect in distributed collaboration
Distributed collaborative teams increasingly rely on online tools for interaction and communication for both social and task-oriented goals. We are expanding recent work linking emotion and affect to collaboration and creativity in order to model how this collaborative communication takes place by examining real-world examples, specifically from the chat logs of an international astrophysics collaboration. We aim to understand how team members express affect and emotion in this medium and the impact that these expressions have on group dynamics, creativity, and problem solving.

Collaborative games for bioinformatics education
We are interested in the uptake of concepts of cyber problem solving specifically among young underrepresented minorities and women, and in better understanding the larger relationships between people, educational games, and infrastructural computational technologies. Collaboration and creative strategies are encouraged and integrated into the gameplay mechanics.
Human-centered biometric security
We study security technology from a human-centered perspective. Our work includes usability evaluation of emerging security technologies, studies of people’s day-to-day password-related practices, and evaluation to determine the key interface design factors affecting user acceptance of biometric security systems.
Dr. Aragon and her colleagues are developing and evaluating a dynamical systems theory of collaborative creativity based on distributed affect and interfaces that facilitate socio-emotional communication.
