Research Areas

Sensor networks, adaptive signal processing, digital communications, wireless networking, biological computing, distributed intelligent systems.

Payman has served on the faculties of the University of Alabama in Huntsville and the University of Washington. He has been a guest editor of the IEEE Transactions on Neural Networks; served as the editor-in-chief of the IEEE Neural Network Council's newsletter and homepage; chaired the 1997 IEEE Computational Intelligence in Financial Engineering Conference; helped with organization of ICASSP'98 and the IEEE Joint Conference on Neural Networks, July 2000 (by invitation), and served on the technical program committee of the 2002 IEEE CAS Workshop on Wireless Communications and Networking. More recently he has been the general co-chair of the 2005 IEEE Swarm Intelligence Symposium. He was with NASA's Jet Propulsion Laboratory from 1997-2005.

While at JPL he also served as affiliate graduate faculty at the Department of Electrical Engineering at Caltech. He is currently an affiliate associate professor with the Dept. of Electrical Engineering, University of Washington.

Awards

Payman has been a recipient of two JPL NOVA awards, as well as four NASA tech brief awards in 1999, 2001, 2002, and 2004 for his joint work on developing a computationally intelligent fast acquisition algorithm for deep space optical communications, and power efficient wireless communication algorithms.

Three pending and provisional patents have resulted from his work.
