Hollow Fiber Membranes

Prof.Chung is a Provost’s Chair Professor at the Department of Chemical and Biomolecular Engineering, National University of Singapore (NUS). His research focuses on polymeric membranes. He has published more than 725 journal papers with citations of > 36700 (by Scopus) and an H index of 97. After working in US industries for 15 years, he joined NUS in 1995. In 2005-2008, he worked as a Senior Consultant for Hyflux Inc., led and built its membrane research team. He became a Fellow in the Academy of Engineering Singapore in 2012 and received IChemE (Institute of Chemical Engineers, UK) Underwood Medal for exceptional research in separations and Singapore President’s Technology Award in 2015. He was a highly cited researcher in Chemical Engineering & Materials Science and Engineering by the Elsevier and Shanghai Global Ranking in 2016 and received Distinction Award in Water Reuse and Conservation from International Desalination Association (IDA) in 2016. He is also a highly cited researcher in the list of Clarivate Analytics in 2018. Dr. Feng is a post-doctoral researcher at the Department of Chemical and Biomolecular Engineering, National University of Singapore (NUS). His PhD and Bachelor (1st class honor) were obtained from the same department. His research experience includes membrane formation mechanisms, advanced membrane fabrication and modifications. He is currently leading an academic-industrial collaboration to develop high performance hollow fiber membranes for ultrapure water production. He has published 9 research articles in Journal of Membrane Science, Environmental Science & Technology and other leading research journals. He also won the Travel Award from Membrane Society of Australasia in 2019.
