Professor Bahram Shafai received the BS and MS degrees in electrical engineering from the Swiss Federal Institute of Technology (ETH) Zurich, Switzerland, in 1976 and 1978, respectively, and the PhD degree in electrical engineering from George Washington University in 1985. He joined the Department of Electrical and Computer Engineering at Northeastern in 1985 and served as the director of the university’s Communications and Digital Signal Processing Center from 1990 to 1992. Since 1996, he has been the director of the ECE Capstone Design Program and its associated laboratory. He has served as associate editor of two major journals. Currently, he is the associate editor of IEEE Transactions on Systems and serves on the conference editorial board of the IEEE Control Systems Society. Professor Shafai has also been a member of the organizing committees for various international and IEEE-sponsored conferences, such as CDC and ACC. He has published one book and more than 150 journal articles and conference papers, and has been the recipient of several honors and awards. His research interests include robust stability and control of multivariable systems, observer theory, identification and estimation, fault detection, time-delay systems, distributed control, robotics and motion control, adaptive signal processing in control, and communications.

Under the direction of ECE Professor Bahram Shafai, a group of capstone students have created an easy to assemble and transport remote-controlled surveillance helicopter. Source: News @ Northeastern
ECE students Saumitro Dasgupta, Mike Fanton, Jonathan Pham, and Mike Willard, built a brain interface to navigate a mobile robot remotely. The team won first place in the senior capstone project competition.
