Bradford Cowles is an aerospace materials and structures consultant to both industry and government agency clients. Mr. Cowles has extensive experience in aerospace propulsion materials, specializing in materials behavior, materials-structure interactions, and life prediction. Mr. Cowles recently retired after 37 years at Pratt & Whitney, where his final position was senior fellow–Discipline Lead for Materials & Processes Engineering. This was the most senior technical position in a 325-person comprehensive materials engineering organization specializing in gas turbine engine materials and processes, including all phases of their development, characterization, and use in products. His responsibilities included oversight of technical projects and technology development programs, resolution of technical and product issues, and strategic planning for future technology and discipline development efforts. Mr. Cowles has extensive experience in titanium and nickel-based superalloys, including directionally solidified and single-crystal materials, as well as in advanced materials such as structural intermetallics. He has extensive expertise in the mechanics of materials, life prediction and damage tolerance methods, and experimental methods related to testing of materials and engine components. Recent focus areas include advanced surface treatments such as laser shock processing as well as materials and structures prognosis technology for gas turbine engines. In 2010, Mr. Cowles focused on developing materials-related strategic plans for a major aerospace company, con-
