Biography

Dr. Chua Kian Jon Ernest is currently working as Assistant Professor, Department of Mechanical Engineering, National University of Singapore. From 2001 to 2006, Dr. Chua served as a Research Fellow at ME department where he and his coworkers conducted studies on time-varying heat transient processes for bioproducts. He has received his Ph.D. in Mechanical Engineering from National University of Singapore, Singapore. In addition, Dr. Chua conducted additional postdoctoral research on the energy-efficient building systems, namely, buildings’ envelop studies and efficient dehumidification systems. In 2006, Dr. Chua left NUS and joined Temasek as a lecturer in the Diploma of Building Technology where he continued his building energy research. In 2008, Dr. Chua returned to NUS and joined ME department as a senior lecturer focusing on teaching. He re-established his research in Biothermal Engineering and building energy system while working closely with another colleague on heat transfer in biofuel hydrogen assisted diesel engine. Presently, Dr. Chua leads two research teams which are attempting to realize a holistic research vision to produce highly efficient thermal processes for energy and environmental nexus. The remarkable aspect of this vision is to employ purely renewable resources, primarily rain-water and sunlight, to provide innovative solutions that are game-changing for green-building ventilation and air-conditioning. Dr. Chua is presently the principal investigators of several key research projects with a total direct research funding of SG$5.2 million. Dr. Chua has hosted a number of specialty seminar/workshops in biothermal heat transfer as well as innovative building energy systems. He has authored and co-authored more than 90 publications and book chapters. His works are highly cited by the global research committee. His total citation count is more than 1200 (from Scopus). His H-index and citations per paper as of September 2014 are 21 and 13.5, respectively. Currently he is serving on the Editorial Board of more than 10 journals.
