Short Description

 
W.O. Wong was awarded a BEng (Hons) degree in mechanical engineering by the Hong Kong Polytechnic in 1987. He worked as a mechanical engineer in the local industry from 1987-1990. He joined the then Hong Kong Polytechnic (now upgraded as The Hong Kong Polytechnic University) in 1990 and has since worked as a lecturer with the Mechanical Engineering Department. Through part-time studies, he obtained a MSc degree in Precision Engineering in 1992 and a PhD in 1997. He was promoted to assistant professor in 1999 and associate professor in 2010. His research interests are vibration analysis and optical metrology with digital holographic interferometry.
