I graduated from ISU in 1964 with a MS degree in physics. Work on processing of gas mixture data obtained by ultrasonic interferometry was conducted under the guidance of Prof. Sam Legvold.
Following this I went directly into the space program as a member of a technical support group with the Boeing Launch Systems Branch in New Orleans, where work involved instrumentation of the first stage of the moon rocket (Saturn V, S-1C stage). Transfer to Huntsville, AL with Boeing led to eventual employment with another NASA contractor, Wyle Laboratories, as a Research Staff Member. Work at Wyle with a cosmopolitan group of engineers resulted in exposure to Aerodynamic Noise Theory and related fluid dynamic measurements and provided motivation for additional course work in fluids and applied math at the University of AL in Huntsville.
Unfortunately, this was best accomplished by transferring to Northrop where I took courses and worked on upper atmospheric (60km) "gravity wave" motions affecting the Space Shuttle reentry environment. The gravity wave work resulted in a NASA certificate and award "....for the creative development of technology...." (1973).
Near the end of the NASA Moon program I transferred to Duke University where the Biomedical Engineering Program provided exposure to pre-med courses in human physiology and engineering courses in medical instrumentation. Because of my fluids and acoustics experience, I elected to do a Ph.D. thesis on focused broadband array design for ultrasonic cardiac sector scanning. The effects of pulse duration and element placement on resolution (main beam dimension) and target ambiguity (sidelobes) were investigated (JASA 61, 1481-1491(1977)).
After graduation, I accepted a post-doc at the National Bureau of Standards (NBS) Electromagnetics Division in Boulder, CO, where I was introduced to the work of Dr. David M. Kerns (JASA 57, 497-507(1975)). To implement Kern's theory for making and extrapolating near field measurements on directional continuous-wave ultrasonic radiators, I spent my post-doc developing a methodology for use of a tank and piezoelectric probe traversing system.
Upon completion of my post-doc, I was transferred to an Acoustics Program at NBS in Gaithersburg, MD. There I continued Kern's work and developed an interest in the non-linear fluid dynamic theory permitting the measurement of the total time-average radiated power of a directional acoustic device (IEEE Trans. on Sonics and Ultrasonics SU-26, 1601-1608(1979)). The NBS (Commerce Department) provided me and my wife the opportunity to visit European acoustics laboratories under diplomatic passport as alternate U.S. delegate to the International Electrotechnical Commission (IEC) in Budapest. Labs visited included the PTB in Braunschweig, Germany, the Technical University of Budapest, Hungary and the NPL and the Royal Cancer Hospital in Great Britain. I achieved career status at the NBS but elected to resign for opportunities in industry.
I was hired as Senior Scientist at ADR Ultrasound where I managed 1-6 people and developed a measurement and evaluation laboratory. I was able to make NBS radiation-force power measurements more cost-effective at low power levels. I also served as U.S. delegate to the IEC in Sydney, Australia and attended an equipment show in Tokyo, Japan.
Subsequently, I have worked for a year as Visiting Associate Professor at Drexel University where I taught some graduate and undergraduate physics and submitted a research proposal. I have also looked into the effect of particulate suspensions on Army optics during an one year civilian appointment. As a temp at Boeing, I looked into ultrasonic methods for evaluating Shuttle payloads. I was recently pleased to see in the Science Citation Index that my references have a modest following in the period 1970 to present.
Currently, I am calling myself a consultant while looking for permanent employment, but may in fact be retired. I am divorced with two sons, Sean and Daniel. I have four grandchildren and one on the way. Sean and his wife Bethany are Visiting Assistant Art Professors at the University of Florida in Gainesville. Daniel has a BA in religion from Washington University and is currently working on dual Masters Degrees at a seminary in Pennsylvania.
