Aaron Stebner, Assistant Professor

Professor Stebner joins the CSM faculty in 2013. He also serves as a board member of the ASM International Organization on Shape Memory and Superelastic Technologies. He received his Ph.D. from Northwestern University and B.S. and M.S. degrees from The University of Akron. Concurrent to his PhD program, he held an appointment as a Lecturer of the Segal Design Institute at Northwestern University. He has been awarded numerous fellowships including being named a Toshio Mura fellow, a NASA Graduate Student Researcher fellow, a Walter P. Murphy fellow, and a fellow of the Predictive Science and Engineering Design Cluster at Northwestern. He has also held several positions in industry, most recently as co-creator of a research and development laboratory for TZ, Inc. - a company specializing in intelligent, networked fastening and sensing solutions using shape memory alloys.

Professor Stebner's research encompasses multiscale characterization and modeling of advanced behaviors exhibited by crystalline materials, such as asymmetry, anisotropy, plasticity, and phase transformations. Fundamental understanding resulting from these efforts is used to inform and advance the chemistry, processing, engineering, and design of new materials and applications, which include shape memory alloys for morphing aircraft structures and biological implants as well as core metals for use in nuclear energy containment and creating clean energy via laser fusion.

In his research, in-situ x-ray, synchrotron, and neutron diffraction experiments are performed and coupled with theoretical calculations, self-consistent micromechanical models, and macroscopic finite element simulations to elucidate mechanics of advanced materials. He also works to advance structural component characterization, design, and optimization using both experiments and simulations.
