Professor of Mathematics Debra Boutin gave two presentations at the Canadian Discrete and Algorithmic Mathematics Conference in Vancouver, British Columbia.

Debra Boutin, professor of mathematics, organized a mini-symposium titled "Graph Colouring" at the Society of Industrial and Applied Mathematics Conference on Discrete Mathematics, in Denver, Colo.

Debra Boutin, professor of mathematics, gave a research presentation "Parameters for Graph Symmetries" at the Center for Communication Research, in La Jolla, Calif. In this talk, Boutin surveyed known and new results on ways of measuring network symmetries. In this survey she not only introduced the audience to various parameters used to quantify symmetries, but showed some of the surprisingly strong connections between them.

Professor of Mathematics Debra Boutin gave a research presentation "Symmetry Parameters for the Lexicographic Product" at the 2016 Joint Mathematics Meeting in Seattle, Wash.

Professor of Mathematics Debra Boutin gave an invited talk on her current research topics to the math students and faculty at Colgate University. Her talk "Network Symmetries" was designed to define a few of the basic ideas in network symmetries and to build intuition by examining how this ideas play out for a number of especially elegant network families.
