Dr. Porter’s areas of technical expertise include physical and mechanical metallurgy, failure analysis, fracture mechanics, materials characterization, and microstructure-property relationships. His experience includes heat treatment, microstructural development, mechanical testing, high-temperature mechanical properties, fatigue, and advanced materials characterization methods. Dr. Porter has a Ph.D. in Metallurgical and Materials Engineering and a B.S. in Mechanical Engineering, both from the Colorado School of Mines. Dr. Porter also has extensive casting and production knowledge from his engineering experiences prior to graduate school.

Prior to joining Exponent, Dr. Porter conducted his Ph.D. work at the Colorado School of Mines (CSM) in the Advanced Steel Processing and Products Research Center (ASPPRC). His research focused on the effects of microstructural evolution on creep-fatigue deformation and damage mechanisms of an advanced structural 25Ni-20Cr austenitic stainless steel (Alloy 709) for use in next generation (Gen-IV) nuclear reactor applications. The research included phase modeling using Thermo-Calc software, microstructural development through heat treatments, low-cycle fatigue and creep-fatigue testing, and microstructural characterization using light optical microscopy (LOM), scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and small-angle neutron scattering (SANS). Dr. Porter’s research included domestic collaboration with the Idaho National Laboratory (INL) and international collaboration with the Australian Nuclear Science and Technology Organisation (ANSTO).

Prior to graduate research, Dr. Porter worked in new product development at ESCO Corp. During his time there, he helped develop two patent-pending steel casting designs from ideation to production, which included extensive CAD modeling with Unigraphics, dynamic finite element modeling (FEM) using LS-DYNA, prototype and production casting tool design, developing and managing manufacturing processes, laboratory testing, fixture design, and field trial support in Brazil.
