Robert Mullen received his B.S. in Structural Engineering and MS in Structural Mechanics from the University of Illinois at Chicago. He received his Ph.D. in Applied Mechanics from Northwestern University. Dr. Mullen was a pre-doctoral fellow at NASA Langley He joint the faculty of Case Western Reserve University in 1980 and is currently the Frank Neff Professor and Department Chair of Civil Engineering; he also has a joint appointment in Mechanical and Aerospace Engineering. Prof. Mullen was a NASA faculty fellow during 1982-1983 and was the associate director of the Center for Adhesives, Sealant and Coatings from 1986 to 1988. He received the Meritorious Service Award from Case Alumni Association in 2005, was one of 17 nominees for the National Society of Professional Engineers Engineering Education Excellence Award in 2000 He received the Jeffcott award for best paper on rotating machinery in 1987 and the ASCE award for outstanding service in 1986.

Prof. Mullen’s research interest are in the area of computer modeling of mechanics systems. He is currently researching the use of interval methods to quatify errors in engineering calculations, the biomechanics of the human face and mechanical behavior of micro mechanical systems. He is the Co-director of the Center for Reliable Engineering Computating at Geogia Tech.

Professor Mullen is a member (and board member Ohio section) of the Construction Management Association of America (CMAA), American Society for Engineering Education (ASEE), and the American Society of Mechanical Engineers (ASME) He is a fellow of the American Society of Civil Engineers (ASCE) and a board member of the Cleveland Section ASCE. Prof. Mullen is a registered professional engineer in Ohio.
