Kim Choon NG, Ph.D.




Professor Kim Choon NG obtained his B.Sc. and Ph.D. from the Strathclyde University (Glasgow, UK) in 1975 and 1980, respectively. He worked briefly at Babcock Power Ltd (Renfrew, Glasgow) and joined the ME Dept. of NUS in 1981. After 34 years at in NUS, he joined the Water Desalination and Reuse Center of the King Abdullah University of Science & Technology (KAUST), Saudi Arabia in 2015 as a full-time faculty. His research interests are in adsorption cooling, innovative air conditioning and dehumidifier systems, seawater desalination, co-generation power systems analysis and harnessing sunlight to liquid fuels by CPV systems. He is keen reader of energy efficiency and its thermodynamics relation to unit cost of resource. He pioneered the use of the heat-driven AD cycle to lower the bottom brine temperature limit of MED processes. Kim Choon is the lead PI for KAUST Cooling Initiative (KCI -2019-2022) that will develop chillers for air conditioning without compressors or use of chemical refrigerants.  He has over 270 peer reviewed journals and conference publications. He is active in professional services, serving as associate editors in three international journals, as well as in the committee for PE examination (Part 1_Mechanical, from 2008 to 2015) of PE Board, Singapore. He has been on visiting professorship to the World Class University (WCU) program of Jeju National University, Korea from 2008-2013 and also as a visiting Imperial Professor to Kyushu University in Japan (2004, 2006). He has published 3 books, 14 book chapters, 16 patents started 3 spin-off companies with licenses from NUS and KAUST. His Google H-index factor is 63, total Google Scholar citations in publication is 13093.
