Dale E. Alexander, Ph.D., P.E.


Senior Director


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.
