Jacob O. Wobbrock is an Associate Professor in the Information School and an Adjunct Associate Professor in the Department of Computer Science & Engineering at the University of Washington, where he directs the MAD Lab comprising students from UW's information science and computer science programs. His field is human-computer interaction, where he focuses on how humans interactively exchange information with machines. He specializes in new user interface technologies, input and interaction techniques, human performance with computing systems, and the advancement of HCI research and design methods. The platforms on which he works include desktop, web, mobile, and surface computing systems. Many of his contributions concern input via text entry, pointing, touch, and gesture, often but not exclusively for people with disabilities. He has co-authored 10 best paper winners and 6 best paper nominees, and is a recipient of an NSF CAREER award and 4 other NSF grants. He is on the editorial boards of ACM Transactions on Computer-Human Interaction and Foundations and Trends in Human-Computer Interaction. He obtained his Ph.D. in Human-Computer Interaction from Carnegie Mellon University in 2006 and his B.S. and M.S. from Stanford University in 1998 and 2000, respectively.
