Harry Martz is the Director for Non-destructive Characterization Institute and a distinguished member of the technical staff at Lawrence Livermore National Laboratory and is a Professor of Practice at the University of California San Diego. Harry is leading a team of scientists and engineers to research, develop and apply nondestructive characterization methods to better understand material properties and inspection of components and assemblies. He has applied x-ray CT to inspect millimeter sized laser targets, automobile and aircraft components, high explosives, explosive shaped charges, concrete, and non-destructive radioactive assay of waste drum contents. Recent R&D efforts include CT imaging for conventional and homemade explosives detection in luggage and radiographic imaging of cargo to detect special nuclear materials and radiological dispersal devices. Dr. Martz has authored or co-authored over 300 papers. Harry and colleagues published a book on X-ray Imaging: Fundamentals, Industrial Techniques and Applications. He has also served on several National Academy of Sciences Committees on Aviation Security and was the Chair of the Committee on Airport Passenger Screening: Backscatter X-Ray Machines. Harry has been co-chair of the Awareness and Localization of Explosives-Related Threats, Advanced Development for Security Applications Workshops. Harry received an R&D Magazine 100 Award for his work on a mobile CT system to nondestructively assay waste drums at Department of Energy sites around the country. He received his M.S. and Ph.D. in Nuclear Physics/Inorganic Chemistry from Florida State University, and his B.S. in Chemistry with a physics minor from Siena Collage.
