Harry Martz is the Director for Nondestructive Characterization Institute and a distinguished member of the technical staff at Lawrence Livermore National Laboratory, Livermore, CA. He is also a professor of practice a t the University of California San Diego. Harry is leading a team of scientists and engineers to research, develop, and apply nonintrusive characterization methods to better understand material properties and inspection of components and assemblies. He has applied computed tomography (CT) to inspect one-millimeter sized laser targets, automobile and aircraft components, reactor-fuel tubes, new production reactor target particles, high explosives, explosive shaped charges, dinosaur eggs, concrete, and nondestructive 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 recently published a book titled 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 joined the Laboratory as a Physicist to develop the area of X-ray imaging and proton energy loss computed tomography for the nondestructive inspection of materials, components, and assemblies. He received his M.S. and Ph.D. in Nuclear Physics/Inorganic Chemistry from Florida State University, and his B.S. in Chemistry from Siena Collage.
