Dr. Bowers specializes in failure analysis, failure prevention, metallurgy, materials science, component life prediction, and engineering risk assessment. He has experience in the medical device, utility, oil and gas, automotive, and consumer electronics/products industries.

While at Exponent, Dr. Bowers has leveraged his technical skills and experience to address a wide variety of client challenges, including failure analysis and root cause investigations, materials selection and process development, medical device regulatory testing and validation, failure mode and effects analysis (FMEA), reliability testing, and utility asset management and condition assessment. He has particular interest in assessing the fracture and fatigue behavior of metallic components and the microstructure-property relationship in materials using techniques such as optical and scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), computed tomography (CT), micro/nanoindentation testing, analytical modeling, and novel mechanical testing methods. Dr. Bowers takes full advantage of Exponent’s technical breadth by assembling diverse, multidisciplinary teams to solve complex problems.

Prior to joining Exponent, Dr. Bowers worked as a postdoctoral fellow at Lawrence Berkeley National Lab, where he studied the thermally and mechanically activated mechanisms of grain boundary migration in face-centered cubic (FCC) metals at the atomic scale. Dr. Bowers completed his Ph.D. research at The Ohio State University in 2014, where he studied the deformation mechanisms and origins of functional fatigue in NiTi-based (Nitinol) shape memory alloys (SMAs) as part of a large research effort involving multiple government agencies and industry partners.

Additionally, Dr. Bowers has authored several technical publications and book chapters, has served as a teaching assistant for undergraduate engineers, and has presented his work at academic and industrial conferences.
