His experience also includes a wide range of technical activities related to the structural health monitoring of civil infrastructure including advanced finite element modeling, instrumentation design, and implementation of monitoring systems, truck load testing, operational modal analysis, and multi-reference impact testing. In addition, he has also worked on the development of risk models to support asset management, customization of risk models for inclusion of state specific data, and assisting with the integration of the developed risk models within an existing software used for bridge management. Dr. Prader earned a PhD, MS, and BS from Drexel University where he concentrated on structural and civil engineering and is a Registered Professional Engineer in Pennsylvania.
