Unnikrishna Pillai, currently half-Full-Professor (half-time since 2010, Full-Professor since 1995) of Electrical Engineering at the Tandon School of Engineering, New York University, joined the Polytechnic Institute of New York (Brooklyn Poly) in 1985 as an Assistant professor. He graduated from the Moore School of Electrical Engineering, University of Pennsylvania with a PhD in Systems Engineering (1985), and prior to that from IIT, Kanpur, India with an MS in Electrical Engineering (1982). He has served as the Electrical Engineering department head for one year in the past (1998-1989) during the Polytechnic years. His research interests include system identification, radar signal processing, synthetic aperture radar (SAR) imaging and identifying moving targets from such radar images and from superfast hypersonic platforms, machine learning technuiques for signal detection and identification in congested and other environments. His other interests include autonomous navigation of ground and airborne moving vehicles as a swarm (driverless cars driving together, moving drones from 'here to there' etc.) and risk estimation for portfolios through cognitive methods where greed/risk are managed for reasonably moderate returns (profit) with long term goal in mind.
Pillai considers it his great fortune to have had the opportunity to work with Prof. Dante C. Youla of Polytechnic, for over 30 years, an expert on a variety of areas spanning more or less the entire Electrical Engineering. Prof. Youla is a remarkable teacher, best mind and working with Prof. Youla has been the highlight of Pillai's technical career and a rewarding 'Zen-like' experience for him in many respects (real highlight of his life being Priya!).
He has coauthored five textbooks/monographs related to electrical engineering and four other e-books. For the classroom, he has produced over two hundred video lectures on YouTube on selected topics to complement his class room lectures so that students have access to key material and more examples.
Unni has also published (Guest editor and producer) two translations of "Bhagavad Gita" in Malayalam into one book form with an introduction by him hoping to spread Bhagavan's (God's) words - atleast the interesting ones - among the moderately literate ... He has also sponsored and produced a music CD containing selected Indian mythology excerpts from classic Kathakali plays performed by some of his favorite artists from Kerala (southwest bottom corner of India).

Method and apparatus for dynamic swarming of airborne drones for , (US 9104201 B1)
A method, system and apparatus to detect when one or more airborne unmanned aerial vehicles (drones) are close to each other, and to take necessary actions to maintain a minimum distance between drones as well as a maximum distance among the drones in a dynamic environment by automatic navigation. A computer method and apparatus for holding a group of drones in a swarm formation by maintaining the group centroid of the group of drones within a tolerance of a predetermined location is also disclosed. Additionally, methods to move a swarm of drones along a predetermined path while maintaining the swarm formation of the drones is also disclosed.
Method and apparatus for automobile accident reduction using loca, (US 9187118 B2)
A method, system, and apparatus to detect when one or more moving vehicles are close to a first vehicle, and to take necessary actions to maintain a minimum distance between vehicles in a dynamic environment by automatic navigation. A computer method and apparatus for automobile accident reduction by maintaining a minimum distance with respect to all nearby vehicles on the road. In addition, methods to synchronously move a group of vehicles on a highway through a swarming action where each vehicle keeps a region immediately around it free of other vehicles while maintaining the speed of the vehicle immediately in front or nearby is also disclosed.
