Experienced materials consultant with demonstrated proficiency in selecting and testing materials, investigating and reconstructing material failures, and developing scientifically supportable recommendations and conclusions. Dr. Alexander’s materials expertise is applicable to all categories of industrial, military, commercial, and consumer products. He also provides opinion testimony as a materials expert in litigated matters in state and federal courts and international venues.
Dr. Alexander’s experience spans a variety of such industry segments as aviation, transportation, power generation, heavy equipment and machinery, medical devices, and household products. He leverages his knowledge of fracture mechanisms, corrosion, wear and degradation, microstructure, physical properties, and material joining to understand and solve problems with both non-metallic materials (polymers, elastomers, GFRP), and metallic alloys, including ferrous alloys (steel, stainless steel, iron-based super alloys), and non-ferrous alloys (aluminum, copper, brass, nickel-based super alloys).
Before joining ESi in 2001, Dr. Alexander worked for ten years as a materials scientist at Argonne National Laboratory’s Materials Science Division. During his tenure there, his research resulted in dozens of publications in peer reviewed journals and invitations to present at international organizations and conferences.
ESi’s extensive aviation experience includes deep expertise in high temperature turbine blade superalloys. We routinely diagnose blade issues such as metallic creep, fatigue cracking, and sulfidation corrosion.
ESi investigated an issue involving the performance of the high temperature superalloy used in the turbine blades of a commercial aircraft engine.
ESi's expertise spans dozens of industries and specializations organized across several practice groups, each staffed by dozens of in-house experts with the technical knowledge, hands-on expertise, and courtroom experience required to execute projects for and with our clients from start to finish.Contact Us
