Karl-Dieter Crisman has degrees in mathematics from Northwestern University and the University of Chicago. He has taught at a number of institutions, and has been a professor of mathematics at Gordon College in Massachusetts since 2005. His research is in the mathematics of voting and choice, and one of his teaching interests is (naturally) combining programming and mathematics using SageMath. He has given invited talks on both topics in various venues on three continents.

Other (mathematical) interests include fruitful connections between mathematics and music theory, the use of service-learning in courses at all levels, connections between faith and math, and editing. Non-mathematical interests he wishes he had more time for include playing keyboard instruments and exploring new (human and computer) languages. But playing strategy games and hiking with his family is most interesting of all.
