David K. Hsu is a Senior Scientist of the Center for Nondestructive
Evaluation and Adjunct Professor of Aerospace Engineering at Iowa
State University. He received his Ph.D. in Physics from Wayne State
University in 1971. He has been engaged in NDE research at ISU since
1984. His main research interests are ultrasonics, nondestructive
evaluation (NDE), and composite materials. He has developed special
ultrasonic transducers with Gaussian and Bessel beam profiles, a
fieldable ultrasonic scanner (the "Dripless Bubbler") for detecting
corrosion, the Computer Aided Tap Tester (CATT) for inspecting
composites, a fieldable air-coupled ultrasonic scanner, and a
generic scanner ("GenScan") for producing manual inspection images
using commercial NDT instruments. The Dripless Bubbler received a
R&D100 award in 1996 and both the CATT and the Dripless Bubbler have
been commercialized. His current research area includes NDE for
composite repairs, degradation and damage of composites and the
application of air coupled ultrasound. Prior to Iowa State, he was a
faculty member in the Department of Physics at Colorado State
University from 1971 to 1984, where he did research on nuclear
acoustic resonance in metals and alloys and studied the properties
of metal hydrides. He has published more than 200 papers, with about
one third of them in refereed journals, and holds seven U.S.
patents.
