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

Principal

Practice Group Director

Materials Practice Group

As Director of the Materials practice, Dr. Dale Alexander oversees materials and analysis personnel and related work across multiple offices.

Prior to joining ESi, in 2001, he worked for 10 years as a research scientist in the Materials Science Division of Argonne National Laboratory. While there his work focused on understanding a variety of radiation effects in metals and alloys including microstructural changes, phase transformations and embrittlement of nuclear reactor pressure vessels via electron microscopic and synchrotron radiation techniques.

Since joining ESi, Dr. Alexander has been active in investigations involving materials issues pertinent to a variety of industries including aviation, automotive, and manufacturing and consumer products. He brings a comprehensive approach to failure analysis and by leveraging the diverse resources of ESi, seeks clear solutions to complex problems offered by clients.

Dr. Alexander is active in many technical and professional societies and has published over 35 articles in refereed journals and conference proceedings.
