Christopher Chao is Dean of Engineering and Chair Professor of Mechanical Engineering at University of Hong Kong (HKU). He received his BSc(Eng) degree in Mechanical Engineering (First Class) from HKU in 1988 and was with the beverage industry 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 (tenured, 2002-2009), Full Professor (2009-2015) and Chair Professor (2015-2018) before he joined HKU in June of 2018.
Prof. Chao is a Fellow of The American Society of Mechanical Engineers (FASME), USA, The Institution of Mechanical Engineers (FIMechE), UK, The Chartered Institution of Building Services Engineers (FCIBSE), UK, The Hong Kong Academy of Engineering Sciences (FHKEng), The Hong Kong Institution of Engineers (FHKIE), and The International Society of Indoor Air Quality and Climate (FISIAQ). He was also an elected member of the ISIAQ Board of Directors and Vice President (Policy) before. He was a member of the Engineering Panel of the Hong Kong Research Grant Council (2011-2017), and has been a vetting member in the Research Projects Assessment Panel (Mechanical Systems and Manufacturing Technology) of the Innovation Technology Commission in Hong Kong since 2013. He is a member of the Steering Committee of the Pilot Green Transport Fund of the Hong Kong Environment Bureau, the Building Committee of the Housing Authority, the Sir Edward Youde Memorial Fund Council, Board of Directors of Cyberport, Board of Directors of HKU Space, Board of Directors of the Engineering forum of HKIE, and the Buildings Appeal Tribunal Panel. He has been serving as Vice President of Hong Kong Institution of Science since 2019 and was Vice Chairman of the HKIE Fellowship Committee (2014/2015) and a co-opted council member (2018/2019). Prof. Chao has been active in Engineering Program Accreditation and was the Chair of the Washington Accord Review Panel for Peru in 2017.
Prof. Chao’s research interests cover a wide range of topics in Thermal and Environmental Engineering including:
Aerosol and gaseous contaminant transport in indoor environments,
Solar and waste heat driven cooling and refrigeration system,
