I received my B. Tech. from the Indian Institute of Technology, Bombay in 1990 and my Ph.D. from Syracuse University , Syracuse, NY in 1996, both in Electrical Engineering. In January 1997 I joined Research Associates for Defense Conversion, Inc. working on a research contract with the Signal Processing Branch of the Sensors Directorate within the Air Force Research Laboratory at the Rome Research Site (It used to be AFRL/SNRT).

I joined the ECE Dept. of the University of Toronto in August 2000 where my primary appointment is with the Communications Group , but I am also cross listed with the Electromagnetics Group . My primary area of research is in the physical layer of wireless communication systems and sensor networks. I am also interested in adaptive signal processing for radar systems.



Research Page : Overview of my group's research goals, current and past work

Adaptive processing in the physical layer in communication systems

Exploiting the spatial and temporal dimensions to improve the quality, capacity and reliability of wireless communication systems.

Enabling cooperation for energy savings in wireless sensor and data reliability and/or access-point networks.

Signal processing for radar systems : The detection, identification and tracking of tactical targets in stressful interference environments using advanced signal processing techniques.

Some specific problems we are working on are:

         Precoding in multiuser downlink communications with a specific focus on practical, linear, schemes with limited feedback.

         Energy efficiency and reliability in access-point and sensor networks with a specific focus on the practical schemes for node cooperation and analysis of cooperation schemes based on error control coding.

         Robust adaptive processing for airborne surveillance radar in stressful interference conditions, especially non-homogeneous clutter conditions.

         The use of waveform diversity in combination with widely distributed apertures for extremely accurate target detection and tracking; one application high frequency surface wave radar (HFSWR) and over-the-horizon radar (OTHR).

         Signal processing techniques to detect concealed weapons using a noise radar

         Modeling and design of radar techniques for Interferometric Synthetic Aperture Radar (with Prof. Georgia Fotopoulos of Civil Engineering)

Personal Interests

    Keeping this little fella out of trouble. Oh! my god! There are two of them!


    Talking about loosing weight

    Hiking, camping, reading (esp. the New York Times and the Economist)

    Cricket! I nearly always begin my day with a quick look at the latest scores, though my son has been pushing me into hockey and basketball.
