Deceased

Floyd Dunn received his Ph.D. from the University of Illinois in 1956. He is a professor emeritus, having retired in 1995, in the departments of Electrical and Computer Engineering, of Molecular and Integrative Physiology, and in the Bioengineering and Biophysics Programs at UIUC and a full-time Beckman Institute faculty member in the Bioacoustics Research Laboratory. His fields of professional interest are ultrasound biophysics and bioengineering.

J. Fry Memorial Award, American Institute of Ultrasound in Medicine; Silver Medal, Acoustical Society of America; Joseph H. Holmes Basic Science Pioneer Award, American Institute of Ultrasound in Medicine; Medal of Special Merit, Acoustical Society of Japan; and University Scholar, UIUC; and IEEE Engineering in Medicine and Biology Society Career Achievement Award.

Floyd Dunn’s work continues the approximately forty years of study in the field of bioultrasonics. Specifically, these studies deal with determination of the ultrasound propagation properties of living systems, viz., sound speed, absorption, attenuation, impedance, as functions of temperature, pressure, media composition; investigation of the physical mechanisms involved in producing reversible and irreversible changes in living systems by ultrasound, viz., thermal, cavitation, mechanical; toxicological aspects of ultrasound exposure; ultrasound metrology; and ultrasound microscopy. A portion of Dunn’s work is peripherally related to molecular nanostructures, one of the main research themes of the Beckman Institute.
