I received my doctorate from the University of Illinois at Chicago in 1982.  My advisor was Louis L. Pennisi.  My thesis was on Operator Theory in Hilbert Space.

Since 1982 I have been teaching in the Mathematics Department at the University of Wisconsin-Eau Claire.  I am now a full professor in that department.  I have taught a variety of courses over the years, ranging from college algebra, liberal arts math, calculus, linear algebra, Fourier analysis, Fourier optics, digital signal processing, image processing, and mathematics & music.

I have published 19 papers on topics in Fourier analysis, wavelet analysis, logic, image compression, image denoising, and mathematics & music.  

I have published six books, they are the following:

1. Fourier Analysis, 1988, Oxford University Press.

2. Fast Fourier Transforms (1st edition), 1991, CRC Press.

3. Fast Fourier Transforms (2nd edition), 1996, CRC Press.

4. A Primer on Wavelets and their Scientific Applications (1st
edition), 1999, CRC Press.

5. A Primer on Wavelets and their Scientific Applications (2nd edition), 2008, CRC Press.

6. Mathematics and Music: Composition, Perception, and Performance, co-author Gary W. Don, 2013, CRC Press.
