My research interests include both math education and graph theory. In the area of graph theory, I am most interested in pursuit games, random graphs, graph Ramsey theory, and extremal graph theory. In the area of math education I am most interested in alternative methods of assessing student learning, particularly as a means of improving access to and equality of education.

Line-of-Sight Pursuit in Strictly Sweepable Polygons

We study a turn-based game in a simply connected polygonal environment between a pursuer and an evader, in which each player can only see the other when the line segment connecting them is contained in the polygon. This work started in the summer of 2011 as part of the IMA and Macalester REU program MAXIMA, for which I was a postdoc advisor to a team of talented students working under the supervision of Andrew Beveridge. The resulting paper has been submitted for publication.
