Leonard J Bond Editor & Author

Dale Esminger attended The Ohio State University and graduated with Bachelors degrees in both Mechanical and Electrical Engineering in 1950. He also undertook post-graduate studies at OSU between 1950 and 1953. Dale began working at Battelle Memorial Institute in 1948, while still a student at OSU, and worked there until his retirement in January 1988. During his time at Battelle he was active in research in ultrasonics. He was involved in about 1,000 different projects relating to ultrasonics, acoustics and related areas. He also holds many patents related to these projects. He was a member of the Acoustical Society of America, Ultrasonics Industry Association, and the American Society for Nondestructive Testing (ASNT).

Leonard J. Bond graduated with his PhD in Physics in 1978 from the City University London. He has experience as an academic, in industry, with national laboratories, as a consultant and expert witness. He started his research career with British Gas, who sponsored his graduate work, which considered models and experiments for ultrasonic Rayleigh wave interactions with defects. His post-doc was sponsored by the UK’s Propellants, Explosives, and Rocket Motors Establishment (PERME), Westcott. He then held a succession of faculty positions at University College London (UCL), where he was a founding member of the UCL NonDestructive Evaluation Center. For his contributions to the field at UCL he was appointed Reader in Ultrasonics. He moved to the USA as a Research Professor at the University of Colorado, and Guest Researcher, NIST (Boulder). He also worked with the University of Denver, Denver Research Institute (DRI), continuing his research in various aspects of ultrasonics. He moved to the Pacific Northwest National Laboratory (PNNL) in 1998, where he was a Laboratory Fellow. He was on a special assignment as the founding Director of the Center for Advanced Energy Studies (CAES) at the Idaho National Laboratory (INL) in 2005-6. In 2007 he returned to PNNL, as a Laboratory Fellow, with a focus on ultrasound measurements in hostile environments. He joined Iowa State University (ISU) as Director of the Center for NDE (CNDE) in July 2012, where he was a Professor of both Aerospace Engineering and Mechanical Engineering. He stepped down from CNDE Director, in May 2018. At ISU he also served as Interim Director for ISU’s Institute for Physical Research and Technology (IPRT), from October 2012 until June 2014. From 2018 he continued as a Professor at ISU engaged in both research and teaching, including coordinating the Minor in NDE. On July 1st 2022 he became a Professor Emeritus, Aerospace Engineering (ISU), and he continues with some research in both ultrasonics and radiography.
