Jim Hollan is Professor of Cognitive Science and Adjunct Professor of Computer Science at UCSD. He co-directs the Distributed Cognition and Human-Computer Interaction Laboratory and the Ubiquitous Computing and Social Dynamics research group. After completing a Ph.D. at the University of Florida and a postdoctoral fellowship in artificial intelligence at Stanford University, I was on the faculty at the University of California, San Diego for a decade. I led the Intelligent Systems Group in the Institute for Cognitive Science. I left UCSD to become Director of the MCC Human Interface Laboratory and subsequently established the Computer Graphics and Interactive Media Research Group at Bellcore. In 1993, I moved to the University of New Mexico as Chair of the Computer Science Department. In 1997, I returned to UCSD as Professor of Cognitive Science.

My research explores the cognitive consequences of computationally-based media. It is motivated by a belief that we are at the beginning of a paradigm shift in thinking about representational media, one that is starting to appreciate the importance of representations that are not only dynamic and interactive but that also adapt to the structure of tasks, the context of activities, and even our relationships with others. The goal is to better understand the cognitive, computational, and social ecology of dynamic interactive adaptive media.

My interests span across cognitive ethnography, distributed and embodied cognition, human-computer interaction, multiscale information visualization, multimodal interaction, and software tools for visualization and interaction. My current work involves four intertwined activities: developing theory and methods, designing representations, implementing prototypes, and evaluating the effectiveness of systems and understanding the broader design space in which they are situated.explores the cognitive, computational, and social ecology of dynamic interactive media as a basis for designing computer-mediated interaction and communication.

My current research is funded by the National Science Foundation (NSF) and the National Institute of Health (NIH). Earlier research was funded by California's Digital Media Innovation Program, Chancellor's Interdisciplinary Collaboratories Program, UC MICRO Program, Darpa, Intel, Microsoft Research, Nissan, NSF, ONR, and Sony.
