Ahmed I. Zayed earned his PhD in 1979 from the University of Wisconsin-Milwaukee. Prior to his position at DePaul University, he was an Associate Chair for Graduate Studies at the University of Central Florida.
Zayed’s research interests include Sampling Theory, Wavelets, Fractional Fourier transform, Sinc Approximations, Special Functions, Integral transforms, and mathematical applications in signal and image processing. He has published 9 books, 17 book chapters, and 106 research articles. He has served on the Editorial Boards of several mathematics and engineering journals, such as the journal of Integral Transforms and Special Functions and the International journal of Fractional Calculus and Applied Analysis. He has received several awards for excellence in research and online course design. He is currently serving as Chair of the SampTA Steering Committee, An International Group on Sampling Theory and its Applications.
