She received her B.S. from Seton Hall University and her Ph.D. from Stevens Institute of Technology. McGuire has been a member of the campus community since 1999. Her mathematical interests are in the fields of combinatorics, network analysis, and graph theory. Specifically, she uses mathematics to create optimal designs for tangible structures under specified constraints. Structures of interest include railway systems, communication networks, postal delivery and sanitation pick-up routes, and rules governing the deployment of law enforcement personnel or military guards in a given geographic landscape. Muhlenberg students often work with Dr. McGuire on such optimization problems.
