Dr. Washer’s research has been featured in Mizzou Engineer magazine.

Mizzou Engineer Article

Dr. Washer’s research is focused on the inspection and condition assessment of civil structures.  He is a nationally recognized expert in the field of nondestructive evaluation (NDE), and is currently conducting research in several areas, including ultrasonic crack detection and ultrasonic stress measurement in gusset plates.  He is also conducting research in coordination with several State Departments of Transportation on the use and implementation of infrared thermography for detecting deterioration in concrete structures.

Dr. Washer is also conducting research related to inspection planning, and risk and reliability-based (RBI) inspection. He is the Principal Investigator for NCHRP 12-82, Developing Reliability-Based  Bridge Inspection Practices, and also works extensively with State DOTs and other government and private agencies on effective inspection planning and condition assessment strategies.  He consults and provides expertise for studies of inspection planning and reliability for aerospace vehicles, nuclear containment and storage, major highway bridges and other civil structures.  He also conducts studies involving the reliability of inspection methods and practices, effective risk-assessment for inspection planning, and bridge inspection quality control / quality assurance (QC/QA).
