Employment HistoryCurrently Professor in the Aerospace Engineering Department at Texas A&M

University (joined December 1989) Research Engineer at NASA Langley Research Center, Mechanics of

Materials Branch from January 1974 to November 1989

Education1973 - B.S. in Mechanical Engineering, North Carolina State University1976 - M.S. in Mechanical Engineering, Stanford University1988 - Ph.D. in Materials Engineering Science, VPI & SU

Research ProgramActively involved in damage mechanics of composite materials. The broad goal is to develop analytical models to explain the response of composites under static and fatigue loads and ultimately to predict the response of potential composite structures without the need for extensive experimental effort. The analytical models range from simple closed form analyses to fully three dimensional nonlinear finite element analyses.
