M.A. Northwestern University, 1983
I earned my Ph.D. in 1987, specializing in Algebraic K-Theory and the
Cohomology of Groups. I taught for four years at Luther College in
I have led several research projects with undergraduates in fractal geometry and the Hausdorff metric geometry. Details of these projects can be found here. Like many other people, I have become fascinated with fractal geometry and chaos. Not only is the subject interesting, but it offers some reasonable problems that are accessible to undergraduates. My interest in fractal geometry has led to recent work, through our REU, to studies in the Hausdorff metric geometry.
Kevin Dennis and I worked together at Luther
College on my first such project in fractal geometry. Aimee Kunnen and I
extended the work Kevin and I did into three dimensions. The work with Aimee
Kunnen was funded by a grant from
In the summer of 2000, I was the PI of a National Science Foundation's Research
Experience for Undergraduates (REU) program. A list of current REU sites in
mathematics can be found here. Other
faculty involved in the 20002 GVSU REU were Ed Aboufadel, Paul Fishback, Jody Sorensen, and Clark Wells. We had a great group in 2000. I worked with Dominic
Braun (then at the
Our REU program received funding from the NSF to continue in the summers
2002-2004. More information can be found at our REU web site. Again, we had a
fantastic group in 2002. That summer Audrey Powers (
In our REU 2003, Christopher Bay (
The 2004 REU once again had my group working on the Hausdorff metric geometry. This time, I worked with Kris Lund (GVSU) and Patrick Sigmon (Wake Forest University). We found some interesting and surprising properties of segments in this geometry, along with connections to the Fibonacci and Lucas numbers and a fascinating property of the number 19. We are currently working on two different papers to submit for publication. The other faculty mentors in the 2004 REU were Ed Aboufadel, Will Dickinson, and Jody Sorensen.
We will be recruiting soon for REU 2005 (pending funding). Please see our REU web site for details as they become available.
Another area of interest is wavelets. My colleague Ed Aboufadel and I have an introductory book Discovering Wavelets, which is now available. The Discovering Wavelets website contains information and links to many interesting sites on the subject.
I am also heavily involved in the Michigan section of the MAA. Our section sponsors many fantastic programs and activities. For example, the High School Visiting Lecturer Program sponsors volunteer lecturers from colleges, business, and industry to visit to high schools in the state and speak on topics in mathematics while the Michigan Mathematics Prize Competition encourages students to develop their interests and abilities in mathematics. I am section chair this year.
