Reverend Dewald is interested in the history of mathematics and enjoys teaching students with "math anxiety." He teaches Elementary Statistics. He is a winner of the Knisely Teaching award.

Dr. Lyons



David W. Lyons

Professor of
Mathematical Sciences


 B.S. Davidson College
Ph.D. University of North Carolina at Chapel Hill

Dr. Lyons has broad mathematical interests in the areas of geometry, topology, algebra, and computer visualization. His current research is in mathematical physics in the area of quantum information theory. His pedagogical scholarship centers on the use of visualization, particularly with animation, for teaching mathematical concepts. Away from the office, he is advisor and master instructor for the Taekwondo Club.
