testers, ballot design systems, secure online architectures, and new approaches for using simulation to evaluate political platforms. Prior to joining MIT’s faculty in November 1999, Selker directed the User Systems Ergonomics Research Lab at the IBM Almaden Research Center, where he became an IBM Fellow in 1996. He has served as a consulting professor at Stanford University, taught at Hampshire, the University of Massachusetts at Amherst, and Brown University, and worked at Xerox PARC and Atari Research Labs. His research has contributed to products ranging from notebook computers to operating systems. His work takes the form of prototype concept products supported by cognitive science research. He is known for the design of the “TrackPoint III” in-keyboard pointing device now found in Compaq, Fujitsu, HP, IBM, Sony, TI, and other computers; for creating the “COACH” adaptive agent that improves user performance (Warp Guides in OS/2); and for the design of the 755CV notebook computer that doubles as an LCD projector. He is the author of numerous patents and papers in refereed journals and conference proceedings. He received his B.S. in applied mathematics from Brown University, his M.S. in computer/information sciences from the University of Massachusetts at Amherst, and a Ph.D. in computer science from the City University of New York.
