Professor William S. Wong is a Professor at the University of Waterloo in the Department of Electrical and Computer Engineering. Wong received his PhD in materials science from the University of California, Berkeley in 1999. Following 10 years as senior member of research staff at the Palo Alto Research Center (formerly Xerox PARC) he joined the faculty at University of Waterloo in 2010. While at PARC, Wong’s research focused on large area electronics where he began programs in printed electronics for Hydrogenated Amorphous Silicon (a-Si:H) Thin Film Transistor (TFT) fabrication, silicon nanowire synthesis and flexible electronics for image sensor and display applications.

Wong has published more than 70 papers and has been granted 50 patents in the area of heteroepitaxy, wide bandgap semiconductor processing, flexible electronics, printed electronics, semiconductor nanostructures, laser processing, and heterogeneous integration. He is a member of the Materials Research Society and an elected member of the Electronic Materials Conference Committee (TMS/EMC). His current research focus is directed toward the development of thin film devices and novel nanocomposite materials for applications in high performance flexible electronics, solid state lighting, image sensors, and energy storage.
