Joe Tringe leads a dynamic group of more than 40 engineers and technicians in the Lawrence Livermore National Laboratory (LLNL) Materials Engineering Division, focused on characterizing a wide range of complex materials, structures, devices and systems.   Techniques of interest to the nondestructive evaluation (NDE) group include x-ray computed tomography (CT), laser and transducer-based ultrasound characterization, microwave interferometry and microwave interrogation of embedded sensors.  Dr. Tringe has led the group since 2017.   From 2003 to 2017, Dr. Tringe was a staff scientist in the Physics and Life Sciences Directorate where he synthesized and characterized devices and materials with novel electrical, optical and molecular transport properties.  He also developed advanced methods for characterizing phenomena associated with energetic materials safety.     Prior to joining LLNL in 2003 he led a group in the Air Force Research Laboratory (AFRL) Space Vehicles Directorate which created and characterized radiation- and defect-tolerant electronic materials, devices and circuits for satellites.   Dr. Tringe has authored more than thirty-five peer-reviewed publications and five U.S. patents.
