Majeed Hayat has active research programs covering a broad range of topics in statistical communication theory, signal/image processing, photodetectors, optical communication, remote sensing, and distributed and cooperative networks. Dr. Hayat is best known for his pioneering work in modeling and understanding impact ionization and noise in avalanche-photodiode (APD) devices, which are used in optical receivers in telecommunications and deep space communication as well as in photon-starved infrared sensors. His work on modeling the stochastic process of carrier multiplication in APDs has significantly enhanced our understanding of how these devices behave, as well as how they perform in optical receivers and single-photon detectors. In 2007, Dr. Hayat spent his half-year sabbatical leave visiting his APD-research collaborators at the University of Sheffield, UK.

In the area of image processing, Hayat and his students have developed a number of key algorithms for nonuniformity correction for infrared thermal imagers. These algorithms, one of which has been patented and licensed to industry, remove what is called the fixed-pattern noise without the need for mechanical calibration mechanisms.

In 2007, Hayat and his collaborators (Santhanam, Gerstle, Simpson and Atwood, see page 24) led a new research initiative on developing a signal-processing method for combined imaging and vibrometry for synthetic aperture radar sensing platforms. This research has already received nearly $1.2M in funding from the departments of energy and defense. In the area of network modeling, Hayat and his collaborators (Bridges, Mostofi and Dietz) have received nearly $1.3M of basic research funding from the Defense Threat Reduction Agency’s program on combating weapons of mass destruction. This includes an $880,000 grant for the 2008 project titled “An Adaptive Probabilistic Approach for Maximal Reliability of Distributed Networks in the Presence of WMD Stressors.”

Dr. Hayat is a recipient of the NSF Early Faculty Career Award, ECE’s 2007 Outstanding Researcher Award, ECE’s 2005 Lawton-Ellis Award, and STC.UNM’s 2007 and 2008 Annual Creative Awards for issued U.S. Patents 7,132,648, 7,217,951 and 7,271,405. He is associate editor of Optics Express and chair of the Albuquerque Chapter for IEEE-LEOS. He currently supervises six doctoral students.
