About

June 27, 2012 by .

This site catalogs my experiments, lectures, and research for my work as a computer science professor at the University of Wisconsin, Eau Claire. My intended audience is my students.

My primary interests are in computer graphics and visualization and mobile software development. My curriculum vitae summarizes my professional career and contains my contact information.

I like to code and I like people too.
