Research Interests:

My research is in the broad fields of harmonic and functional analysis. In particular, I work on problems involving redundant systems which are called frames in Hilbert spaces. I also work on problems involving sampling theory, wavelets, computer vision, and fractals generated by iterated function systems. Click here for my publications and recent activities.

Please contact me if you are an undergraduate or graduate student interested in a reading course or research project in any of these areas.


RAMP UP seminar :

The Resources for Alternative Methods in Pedagogy for University Professionals (RAMP UP) seminar is a place where we share new ideas, techniques, and technologies being used in the classroom. We concentrate on the concrete and specific aspects involved with bringing something new to your class. Meetings will be announced on the Mathematics Department Events Page.


Mission Prime :

Mission Prime is an educational video game that gives students a more conceptual experience with optimization problems such as those seen in the first semester Calculus course. The game was designed and built through a collaboration between the OU K-20 Center's Digital Game Based Learning (DGBL) Team, the Math Department, and the Department of Communication.

Publications resulting from the Mission Prime project are listed here.


OU Women in Mathematics:

Committee W is the OU Mathematics Department's organization in support of women in mathematics.

Frames for Undergraduates:

This book was written to be an accessible introduction to the intriguing and rapidly evolving subject of frame theory. It can be used in teaching either a special-topics course about frames or a second linear algebra course, where the frames serve as examples to the theory. This book could also serve as a reference for students doing research projects about frames.
