Dr. Woon Siong Gan obtained his PhD at the age of 24. He completed his B.Sc. in Physics in 1965, his DIC in acoustics & vibration science in May 1967, and his Ph.D. in acoustics in February 1969, all from the Physics Department of the Imperial College London.His PhD thesis pioneered topological phase transition. IN 1966 he coined and invented the name transport theory in condensed matter physics. His PhD thesis also played a role in the founding of the field of condensed matter physics. Today transport theory is the foundation of theoretical design of materials. It is also an important theory in condensed matter physics and is related to phase transition.From 1970 to 1979, he was an associate professor at the Physics Department of Nanyang University in Singapore. From 1979 to 1989, he was a practicing acoustical consultant. In 1989, he founded Acoustical Technologies Singapore Pte Ltd, a research & technologies company engaging inultrasound technologies, especially acoustical imaging. The company has since developed and patented the scanning acoustic microscope (SAM) and the surface acoustic wave (SAW) devices. Besides research and development works, he is also involved in fundamental research on transport theory approach to phase transition and phase transition as a transport phenomenon.He has published several papers on acoustical imaging,and the applications of gauge theory to acoustics.He is also the author of the books Acoustical Imaging: Techniques and Applications for Engineers.,published by John Wiley & Sons, New Acoustics,based on Metamaterials,published by Springer, Gauge Invariance Approach to Acoustic Fields, published by Springer, Signal Processing and Image Processing applied to Acoustical Imaging, published by Springer, Time Reversal Acoustics, published by Springer, and Nonlinear Acoustical Imaging published by Springer.
