Professor of Mathematical Sciences
A.B. in Mathematics, University of Chicago, 1984.
Ph.D. in Mathematic, Brandeis University, 1990.
Dr. Ralph Bremigan joined the Department of Mathematical Sciences at Ball State in 1992. In addition to broad teaching interests, he has served in many administrative assignments in the Department, including Undergraduate Programs Director, Assessment Director, and Assistant Chair.
