Dr. Prosser joined NASA Langley Research Center (LaRC) in 1987 as an Aerospace Technologist in the Nondestructive Evaluation Sciences Branch. In November 2005, he joined the NASA Engineering and Safety Center as Discipline Expert for Nondestructive Evaluation (NDE). At LaRC, he has served as technical lead and program manager for the research and application of NDE and Structural Health Management (SHM) systems for aerospace vehicles. Dr. Prossers research is in the field of ultrasonic and acoustic emission sensing techniques, most recently leading to the successful development and implementation of a system to detect impacts on the Space Shuttle wing leading edge. He has led NASA, industry, university and government agency teams to implement NDE and SHM systems for a variety of NASA programs including the Space Shuttle, International Space Station, X-33, and Aerospace Vehicle Systems Technology Program.

Dr. Prosser was the 1997 recipient of the NASA Floyd Thompson Fellowship, a 2003 recipient of a NASA Superior Accomplishment Award for efforts during the Columbia Accident Investigation, and a 2005 recipient of NASAs Exceptional Achievement Medal. He is past Chair and a Fellow of the Acoustic Emission Working Group and is also the Scientific Editor of Structural Health Monitoring: An International Journal.

Dr. Prosser has authored over 70 referenced publications and internal technical reports and has received four patents. He received his B.S. degree in Math and Physics from the College of William and Mary and his M.S. and Ph.D. degrees in Materials Science and Engineering from Johns Hopkins University.
