Brad A. James, Ph.D., P.E.

Dr. James is the Director of Exponent’s Materials and Corrosion Engineering Center. He specializes in failure analysis, metallurgy, materials science, fracture, fatigue, material degradation, corrosion, life prediction, and design.

Dr. James has experience within the medical device, pipeline, chemical processing, energy, automotive, fire protection, aerospace, and electronics industries. He helps both industrial and legal clients solve complex problems, as well as interact with governmental agencies such as the FDA, NHTSA, and the NTSB. In particular, Dr. James has helped dozens of manufacturers design and validate their implants and medical devices. Dr. James has specific interest in fractography, fracture mechanics, wear, corrosion, embrittlement phenomena, microstructural development, heat treatment, material selection, and welding and joining.

Dr. James serves as a Lecturer for the Stanford University Material Science Engineering Department, where he teaches a graduate-level engineering failure analysis course. Dr. James also teaches graduate–level failure analysis and fracture mechanics courses as an Adjunct Professor for the Santa Clara University Mechanical Engineering Department. He has taught several courses for The American Society for Materials (ASM International) involving failure analysis, design, and life prediction/validation of medical devices, and has been a Visiting Lecturer at San Jose State University. Prior to joining Exponent, Dr. James was employed as a Research Engineer, Materials Performance Division, at the Babcock and Wilcox R&D Center.
