Payman Arabshahi is Associate Professor, and Associate Chair for Advancement at the University of Washington’s DepartmentElectrical & Computer Engineering; Director of Innovation of Learning Programs at the UW’s Office of Innovation (CoMotion); and a principal research scientist with the UW Applied Physics Laboratory. From 1994-1996 he served on the faculty of the Electrical and Computer Engineering Department at the University of Alabama in Huntsville. From 1997-2006 he was on the senior technical staff of NASA’s Jet Propulsion Laboratory (JPL), in the Communications Architectures and Research Section, working on Earth orbit and deep space communication networks and protocols, and design of planetary exploration missions. While at JPL he also served as affiliate graduate faculty at the Department of Electrical Engineering at Caltech, where he taught the three-course graduate sequence on digital communications. Arabshahi has been the co-founder of, or advisor to, a number of technology startups. His interests are in entrepreneurship education, innovation readiness, underwater and space communications, wireless networks, data mining and search, and signal processing.

Research Interests

Underwater and space communications, wireless networks, power system optimization, smart grid, data mining and search, and signal processing.
