4 Member Transportation Research Board - Committee AFF40: Field Testing and Non-Destructive Evaluation of Transportation Structures Reviewer: American Society of Civil Engineers Journal of Structural Engineering American Society of Civil Engineers Journal of Bridge Engineering Computer-Aided Civil and Infrastructure Engineering Smart Structures and Systems Professional Experience Long-Term Bridge Performance Program (Federal Highway Administration) Technical lead for IIS team serving the Federal Highway Administration on their Long-Term Bridge Performance (LTBP) Program. Responsibilities include: Contributed to the development and execution of a design of experiments approach to identification of bridges to be included in the program. Conducted bridge documentation studies for advanced data mining and analysis beyond National Bridge Inspection level data. Field team lead for data collection on 12 bridges in the Mid-Atlantic region (Fall 2014). Led reorganization and development of the LTBP Protocols a suite of 150 protocols for data collection, reduction and processing as part of the LTBP Program. Logistics, coordination, and publication development International Bridge Study (Rutgers University) Field technical lead and lead coordinator for a 2-year bridge testing effort including collaboration from experts in Austria, Japan, China, Korea, and England as well as domestic teams from Princeton University, Georgia Tech, Utah State, Olson Engineering, Rutgers University, Drexel University and University of New Hampshire.
