Short Description
Prof. Christopher Chao received his BSc(Eng) degree in Mechanical Engineering (First Class) from HKU in 1988 and worked for Swire Industrial Division from 1988-1990. He was awarded the Sir Edward Youde Memorial Fellowship for Overseas Studies in 1990 and obtained his M.S. and Ph.D. degrees in Mechanical Engineering from The University of California, Berkeley, USA, in 1992 and 1994, respectively. He was an Assistant Professor at the Hong Kong Polytechnic University from 1995-1997 and joined The Hong Kong University of Science and Technology (HKUST) in 1997 moving through the ranks of Assistant Professor (1997-2002), Associate Professor (2002-2009), Full Professor (2009-2015) and Chair Professor (2015-2018) before he joined HKU in June of 2018. He was Associate Dean (Research and Graduate Studies) from 2011-2014 and Head of Mechanical and Aerospace Engineering from 2014-2018 when he was at HKUST, and Dean of Engineering from 2018-2021 when he was at HKU.
Prof. Chao’s research is in thermal and environmental engineering covering areas of bioaerosol dispersion, deposition and resuspension in indoor air and the impact on infectious disease transmission; solar and waste heat driven advanced cooling systems; passive radiative cooling; nanofluid and bioinspired heat transfer. He has published more than 170 journal papers. Prof. Chao has been serving as regional editor and editorial board member in several major journals in Built Environment and Energy. He is a Fellow of several professional societies including the Hong Kong Academy of Engineering Sciences and American Society of Mechanical Engineers.
