Faculty Emeriti

Dr. Wu has been considered one of the internationally renowned experts in nonlinear physics, soliton physics, and the biological physics. He has achieved several important discoveries and inventions. Particularly, he and his mentor professor Rudnick discovered non-propagating hydrodynamic solitons in 1983; this achievement was listed as one of the most important achievement in Physics Acoustics in "Acoustical Society of America 75th Anniversary Time- Line." He has published more than 100 papers in Physical Review Letter, the Journal of Acoustic Society, Ultrasound in Medicine and Biology, the Physics in Medicine and Biology and the Advanced Drug Delivery Reviews. He is a co-author of a book entitled "Emerging therapeutic Ultrasound" published in 2007 by The World Scientific Publisher. He is also the co-owner of the following patents: Implant debris detection, Methods for the delivery of compounds to cells, Ultrasonic control for aquatic plant management, Piezoelectric Vibrational Energy Harvesting Systems Incorporating Parametric Bending Mode Energy Harvesting.

Dr. Wu has a B.S. degree in Physics from Nanjing University and M.S. and Ph.D. degrees in Physics from University of California, Los Angeles. He joined the University of Vermont in 1987. Dr. Wu is a Fellow of The Acoustical Society of America and a Fellow of The American Institute of Ultrasound in Medicine. He is also an elected member of Vermont Academy of Science and Engineering. Dr. Wu has been a professional consultant for NRG, BFGoodrich, Gillette, Abott, and Hewlett Packard Co. Dr. Wu applies ultrasound and optics in biology and medicine.

Dr. Wu has been a fellow of Acoustical Society of America since 1991 and American Institute of Ultrasound in Medicine since 1996.
