James D. Connolly

Senior Principal

 
Experience

James Connolly is an expert in materials failure analyses and remediation with more than forty years of experience in detailed microscopical, spectroscopical, chemical, and physical studies of construction materials. His experience also includes specification review, product and patent development, project management, and basic research.

Mr. Connolly retired as a senior principal of Wiss, Janney, Elstner Associates in January 2008. He served as manager of the Materials Science and Engineering group from 1987 to 2002. Prior to joining WJE in 1973, Mr. Connolly was an associate research chemist at Portland Cement Association (PCA) Research and Development Laboratories. He has lectured on coatings and sealant performance, concrete durability, chemical admixtures, and chemical and petrographic analyses for several universities and the Portland Cement Association.
