James D. Hollan is professor of cognitive science and adjunct professor of computer science at the University of California, San Diego. In collaboration with Professor Edwin Hutchins, he directs the Distributed Cognition and Human–Computer Interaction Laboratory at UCSD, and co-directs the Design Lab. Hollan has also spent time working at Xerox PARC and at Bellcore. He was elected to the CHI Academy in 2003 and received the ACM SIGCHI Lifetime Research Award in 2015. His research explores the cognitive consequences of computationally based media. The goal is to understand the cognitive and computational characteristics of dynamic interactive representations as the basis for effective system design. His current work focuses on cognitive ethnography, computer-mediated communication, distributed cognition, human–computer interaction, information visualization, multiscale software, and tools for analysis of video data. His current research is funded by the National Science Foundation (NSF)
