Doug Peterson, Ph.D., Associate Professor Emeritus
B.A, SUNY at New Paltz
M.A. University of Washington
Ph.D. Texas A&M University

Dr. Peterson taught in both the Department of Computer Science and the Department of Mathematics for 24 years. His general area of interest is discrete mathematics and its applications to computer science. His research is in graph theory and he is currently working on problems involving the existence of Hamiltonian cycles in planar graphs.

Dr. Peterson is now a Senior Lecturer in the Department.
