I am a Full Professor and the Chair of the Department of Mathematical Sciences, DePaul University, Chicago, Illinois, the 10th largest private university and the largest Catholic university in the United States. I came to Depaul University in September 2001 to chair the department. Prior to that, I was as Associate Chair for Graduate Studies at the Department of Mathematics, the University of Central Florida, Orlando, Florida (UCF).
The Department of Mathematical Sciences is in the College of Science and Health. It is one of ten colleges of DePaul University.
I have taught a wide spectrum of courses ranging from college algebra to graduate courses on functional analysis, special functions, wavelets, and history of mathematics which I teach as a hybrid online course.
My general field of research is applied mathematical and harmonic analysis. Within this general field, my focus has changed over the years to cover several subfields, such as generalized functions, Schwartz distributions, special functions and orthogonal polynomials, integral transforms, wavelets, sampling theory in the sense of Whittaker-Shannon-Kotel'nikov sampling theory and its applications in signal and image processing. Currently, I am serving as the Chair of the Steering Committee of SampTa which stands for Sampling Theory and Applications..
