Abdul Jabbar Hassoon Jerri (July 20, 1932) is an Iraqi American physicist and mathematician, most known for his contributions to information theory in general, in particular to the understanding of the Gibbs phenomenon. He has written four books and authored over forty papers in his area.
He earned a B.Sc. in physics at the University of Baghdad (1955) and M.S. in physics from Illinois Institute of Technology (1960) in Chicago where he continued to work in the research group (1960–63). He also earned a Ph.D. in mathematics from Oregon State University (1967) on the thesis On extensions of the generalized sampling theorem. Jerri joined the faculty at Clarkson University in Potsdam, NY (1967), where he worked since, becoming professor emeritus (2008).[1] He also had visiting positions at American University in Cairo where he established the study programs in mathematics and computer science (1972–74). He was director of the mathematics study program at Kuwait University (1979–80). Jerri was Fulbright Scholar at the Sultan Qaboos University in Muscat, Oman (1997), and a second time, at the Yarmouk University in Irbid of Jordan (2001).
His main research areas have been integral transforms, discrete transforms, sampling expansions, Gibbs phenomena, transform-iterative methods for nonlinear problems, and operational sum methods for difference equations.[2] He is the founding executive editor of Sampling Theory In Signal And Image Processing - An International Journal.[3]
