Ahmed I. Zayed

Ahmed I. Zayed is a Full Professor and Chair of the Department of Mathematical Sciences at DePaul University's College of Science and Health in Chicago, Illinois. He joined DePaul University in September 2001 after serving as Associate Chair for Graduate Studies at the University of Central Florida. His academic journey began with a PhD in Mathematical Sciences from the University of Wisconsin-Milwaukee in 1979.

Dr. Zayed's research spans the breadth of applied harmonic analysis, with particular expertise in Sampling Theory, Wavelets, Fractional Fourier Transform, Sinc Approximations, Special Functions, and Integral Transforms. His work bridges theoretical mathematics with practical applications in signal and image processing. Over his distinguished career, he has published 9 books, 17 book chapters, and 106 research articles, establishing himself as a leading authority in his fields of interest.

An analysis of his 15 most recent publications reveals a consistent focus on advanced mathematical transformations and their applications. His research demonstrates strong connections between classical harmonic analysis and modern signal processing techniques, with particular emphasis on fractional transforms, wavelet theory, and energy concentration problems. The publications show a clear trajectory toward increasingly sophisticated mathematical frameworks for signal analysis and reconstruction.

Dr. Zayed has served on the editorial boards of prestigious journals including the Journal of Integral Transforms and Special Functions and the International Journal of Fractional Calculus and Applied Analysis. He has received multiple awards for excellence in research and online course design. Currently, he serves as Chair of the SampTA Steering Committee, an international organization dedicated to Sampling Theory and its Applications.

His collaborative network is extensive and global, spanning 19 countries with 45 documented collaborators. This international reach has significantly influenced the direction and impact of his research. Dr. Zayed teaches a wide range of courses from college algebra to graduate-level topics in functional analysis, special functions, wavelets, and the history of mathematics, which he delivers as a hybrid online course.
