Brief

Professor S K Tang obtained his BSc(Eng) from the Mechanical Engineering Department of The University of Hong Kong in 1987. He finished his PhD specializing in acoustics and fluid dynamics from the same department in 1992.
Professor Tang joined the Department of Building Services Engineering, The Hong Kong Polytechnic University in July 1993 and since then has been involved in teaching subjects related to the Built Environment and Acoustics. He is currently the leader of the Building Acoustics and Vibration research group in the Department and is member of a number of research centres in the University. He is also active in organizing acoustics conferences and providing services to the industry. Professor Tang has published over 40 research papers in SCI journals denoted to the science and applications of fluid mechanics, acoustics and mathematics..
