McDowell received his M.S. and Ph.D. in Mechanical Engineering from the University of Illinois in 1981 and 1983, respectively. Dr. McDowell is Regents' Professor and Carter N. Paden, Jr. Distinguished Chair in Metals Processing in the School of Materials Science and Engineering and the Woodruff School of Mechanical Engineering at Georgia Tech. At Tech, he has served as Director of the Mechanical Properties Research Laboratory since 1992, and as Chair of the Materials Council since 1994.  McDowell's research focuses on the synthesis of experiment and computation to develop physically-based constitutive models for nonlinear and time-dependent behavior of materials, with emphasis on wrought and cast alloy systems.  Phenomena of interest include cyclic plasticity and fatigue, finite strain plasticity, defect field theories, behavior of foams and honeycomb materials, microstructurally small fatigue crack behavior, creep-fatigue -environment interaction, time-dependent fracture, nano-mechanics with focus on interfaces, and multiscale modeling. As Co-Director of the NSF-sponsored Center for Computational Materials Design, a joint Penn State-Georgia Tech I/UCRC, he is actively pursing development of strategies for multifunctional design of materials. McDowell currently serves on the editorial boards of several journals, and is co-Editor of the International Journal of Fatigue.  A Fellow of SES, ASM International, and ASME, David is a recipient of the 1997 ASME Materials Division Nadai Award for career achievement and the 2008 Khan International Medal for lifelong contributions to the field of metal plasticity.
