Piezoelectric Ultrasonic Transducers and Sensors: Design, Prototyping and Measurement
He is expert in the design of ultrasonic transducers (MHz range medical/industrial, acoustic or vibration sensor/actuators). Typical applications are, medical ultrasound imaging probes, medical diagnostic sensors, medical ablation tools by high energy focused ultrasound, eye surgery sensors, eye motion sensors,…
Industrial Utilities (Equipment, Operation, Maintenance); Energy Conservation; Vibrations
Expert worked as a staff mechanical engineer at what was the world's largest single site producer of PET. The staff supported operations and maintenance departments throughout the facility, with heavy emphasis on the utilities department. Troubleshooting centrifugal pumps was a…
Mechanics (Stress, Dynamics, Test), Modeling (FEA, CFD, Chemical), Machine Design, Controls
At Cessna, Expert designed the pressure cabin, empennage, and main spar carry through for the 441 Conquest and 650 Citation 2. His other engineering responsibilities included stress measurement (strain gauges, brittle coatings), solids modeling (NASTRAN), and FAA certification report authoring.…
Polymer Rheology and Plastics Processing
Expert is currently working on constitutive modeling of the extensional behavior of molten plastics. He has developed models that allow the behavior in extension to be inferred from measurements in exponential shear. The material behavior in exponential shear is measured…
Springs, Wire Products
Expert is familiar with many methods of cost reduction in mechanisms. As an expert in the area of mechanical devices, he spends a large amount of his time analyzing different loading points, alternate types of springs, and minor changes to…
Material Analysis/Spectroscopy
During the past 15 years, Expert's research has become increasingly oriented toward vibrational spectroscopy, particularly Fourier transform infrared (FT-IR) spectroscopy. In the early 1980s, he developed modern step-scan FT-IR instrumentation for photoacoustic and photothermal spectroscopy of surfaces and opaque or…
