Matthew P. Miller is a Professor in the Sibley School of Mechanical and Aerospace Engineering at Cornell University. He joined the Sibley School faculty in 1994 after receiving his Ph.D. from the George Woodruff School of Mechanical Engineering at Georgia Tech. Miller received a B.A. in Geology from the University of Colorado in 1979 and a B.S. in Mechanical Engineering from the Colorado School of Mines in 1988. In 2012 Miller was named Associate Director of the Cornell High Energy Synchrotron Source (CHESS). Powered by the Cornell Electron Storage Ring (CESR), CHESS is an NSF-funded x-ray user facility located on the Cornell campus employing over 100 scientists, engineers, and other personnel. Much of Miller’s focus at CHESS has been on the creation of new high energy x-ray capabilities for advanced experiments on structural and energy-related materials. Miller’s research focuses on the experimental characterization of the mechanical behavior of materials to build new modeling capabilities for processes such as plasticity, fracture and fatigue. Over the past decade, this work has involved using high energy synchrotron x-rays to probe the microstructural and micromechanical evolution of metallic materials in real time. Miller and his students have built and implemented in situ mechanical loading and heating capabilities at CHESS and at sector 1 of the Advanced Photon Source. Working with computational collaborators, Miller’s group has examined specimens under monotonic and cyclic loading at ambient and high temperatures. For their paper describing the complex multiaxial crystal-scale stress states that they observed in polycrystalline titanium (Ti-6-4) using high energy x-rays, Miller and co-authors won the ASM International Henry Marion Howe Award in 2009 for the Best Research Paper in Metallurgical and Materials Transactions. In addition to ASM, Miller is a member of ASME and ASEE. He is on the Editorial Advisory Board of the International Journal of Fatigue and is on the Review Board for the journal, Integrating Materials and Manufacturing Innovation. Miller has served on the APS Users Organization Steering Committee. He is currently on the APS Sector 1 Beamline Advisory Group and co-authored the Sector 1 Science Case for the current APS upgrade.
