Gabriela Marcu is a PhD candidate in the Human-Computer Interaction Institute at Carnegie Mellon University. Her research spans the areas of ubiquitous computing, applied sociology, and mental health. She uses action research to study and affect the intersecting roles of ubiquitous technology and face-to-face collaboration in the context of mental health services. She has designed a system that uses a network of tablet devices to enhance evidence-based clinical practice by supporting the collaboration of various stakeholders around patients’ behavioral data. Her dissertation work involves studying the impact of this system on the social interactions of real stakeholders, to learn how mobile systems can improve mental health services by encouraging more face-to-face collaboration. Gabriela received her B.S. with Honors in Informatics from the University of California, Irvine.
