Professor

MA in Biomedicine

Professor of Mathematics

Owen joined the Eastern Mennonite faculty in 1999 after teaching at Northwestern College (Iowa) for three years. He earned a bachelor’s degree in mathematics with secondary certification at Messiah College in Grantham, Pa., and a master’s degree and Ph.D. in mathematics at the University of Delaware in Newark. His graduate training is in combinatorics, and he has recently starting writing a Discrete Math textbook with Deirdre Smeltzer and Felix Lazebnik. He coauthored the geometry textbook *Methods for Euclidean Geometry*, published in 2010 by MAA. His hobbies include playing basketball, bridge, and watching NFL football. Owen and his wife Barbara married in January 1990, with son Cameron born in 1998 and daughter Lily in 2001. The family attends Weavers Mennonite Church in Harrisonburg, Va.
