- Research in wireless communications systems.
- Dr. Fam's research focuses on digital signal processing. He and his student developed the interlaced chirp Z transform method. This is a new approach towards achieving non-uniform resolution in the frequency domain. The approach is based on using multiple Chirp Z Transforms which are of different resolution and carefully staggered to avoid overlapping of samples. This method proves to be computationally more efficient than other existing non-uniform frequency resolution methods.

- Dr. Givone is an expert in switching circuit theory, automata theory, and digital systems. He is the author of an internationally recognized textboot, "Digital Principles and Design."
Raj Kaul: System modeling using engineering mathematics
- Dr. Kaul is interested in fractal phenomena, wave propagation in periodic structures, wavelets, elasticity and piezoelectricity. He and his students model these systems using engineering mathematics.
- The Wireless Networks and Embedded Systems (WNES) Laboratory was founded in 2007 within the Department of Electrical Engineering, and currently includes
three Ph.D. and several M.S. students conducting leading-edge research in
wireless networking and communications, embedded systems, and network
optimization and control. Current funding sources include the University at
Buffalo and the US Air Force Research Laboratory. The laboratory has
recognized expertise in the design, modeling, optimization, simulation, and
deployment of wireless sensor networks, and in experimental development and
measurement. In particular, ongoing research projects include underwater
acoustic networking, cognitive radio networks, and wireless multimedia
sensor and actor networks.

- Dr. Soumekh is an expert in radar and medical image processing. He is especially recognized for his work in analyzing synthetic radar images. He is funded by the AFOSR. He is the Director of the SAR High Performance Computing Laboratory. The objective of this laboratory is to develop high-speed signal processing and image formation algorithms for Synthetic Aperture Radar (SAR) systems. Under the sponsorship of the Air Force Office of Scientific Research, a High Performance Computing (HPC) laboratory is established for analyzing the merits of various advanced SAR data collection and information processing algorithms such as Continuous Phase Modulation (CPM) chirp radar signaling and PRF staggering schemes for Electronic Counter Counter-Measure (ECCM), along-track monopulse SAR for Moving Target Detection (MTD), rejection of Radio Frequency Interference (RFI) in FOliage PENetrating (FOPEN) SAR, alias-free processing of wide-beamwidth FOPEN SAR data, reconnaissance with Circular SAR (CSAR), and parallel architectures for near real-time image formation (Range Stacking) in FOPEN and Ground PENetrating (GPEN) SAR systems.
- The SAR HPC laboratory is intended to establish the means by which the collaborative efforts between Dr. Soumekh and the Air Force and Navy laboratories are continued. It is anticipated that this collaboration would not only enhance the quality of research-related education at University at Buffalo but also would yield results which are of significance to the research programs of the Department of Defense.
