Electrical & Computer Engineering


Unnikrishna Pillai, currently Professor of Electrical and Computer Engineering at Polytechnic School of Engineering, New York University was recently elevated to IEEE Fellow in recognition of his contributions to "adaptive signal processing and radar systems". Dr. Pillai joined the Electrical Engineering department of Polytechnic Institute of New York (Brooklyn Poly) in 1985 as an Assistant professor after graduating from University of Pennsylvania with a PhD in Systems Engineering (1985), and from IIT, Kanpur, India with an MS in Electrical Engineering in 1982. His research interests include adaptive signal processing, synthetic aperture radar (SAR) imaging,radar signal processing, and among other things he has coauthored five textbooks and monographs related to electrical engineering. Within the classroom, he has started generating short video sessions to complement his lectures, wherein students can review key material and examples and work out problems before and after class sessions.
