The research contributions have helped advance the discipline of computational geometry by finding better algorithms to solve various problems.
My work on the AP development committee helped move high school Computer Science classes to an object-oriented approach more in line with current college courses. A number of my activities were aimed at helping high school teachers make that transition.
Teaching in the DIMACS Reconnect program has helped professors in small colleges learn about an interesting new research area that they can explore themselves and can share with their students. It has rekindled an interest in research in some of them.
My hope is that the discrete mathematics textbook will help computer science students learn
discrete math by applying it to problems that they care about. I hope that it will have an
impact on the way that discrete mathematics is taught.
