# Owen Byer

Department Chair

Professor of Mathematics

Professor

Owen 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. He first taught at Eastern Mennonite in 1991 as a sabbatical replacement while on leave from graduate school, and then returned for a full-time position in 1999. His graduate training is in combinatorics (graph theory, specifically), and he is currently coauthoring a Discrete Math textbook to explain all he knows about the subject! His hobbies include playing basketball, bridge, and watching NFL football. Owen and his wife Barbara were married in January 1990, with son Cameron born in 1998 and daughter Lily in 2001. The family attends Weavers Mennonite Church in Harrisonburg, Va.

Owen is currently chair of EMU’s Mathematical Sciences department and will be serving as President of EMU’s faculty senate in 2014-15.
