Curtis J. Schroeder

Associate III

 
Experience

Curtis Schroeder joined WJE in March 2019 with a background in inspection and evaluation of steel bridges. Dr. Schroeder is skilled in advanced inspection techniques for the fabrication of new welded steel structures and the evaluation of existing steel structures using fitness for service (FFS) assessments. He completed his Ph.D. with research on the use of phased array ultrasonic testing (PAUT) of steel bridge welds. Prior to his work as a research assistant, Dr. Schroeder worked for five years at Fish & Associates, Inc. (now Fickett Structural Solutions), where his responsibilities were centered on nondestructive testing research using PAUT and writing engineering guidance documents for improved fatigue and fracture design of steel structures and FFS evaluation of members with existing flaws. Dr. Schroeder also has aided in the development, revision, and instruction of training courses in welding and bridge inspection.
