With more than 20 years of experience in water and wastewater treatment, Young Chul Choi, PhD, PE, is pursuing the development of innovative technology solutions around the water–energy nexus to improve water reuse and energy efficiency of water treatment and enable valuable resource recovery from wastewaters. 

The current water technology program portfolio includes projects to develop low-energy, membrane-, or solvent-based process technologies for desalinating waters with high salinity or dissolved-solids content (e.g., produced waters from deep-well formations in the oil and gas and carbon sequestration sectors) and an anaerobic membrane bioreactor process to produce energy from waste organics in aqueous streams.  Other projects include the development of novel fouling-resistant membranes and a novel membrane-based electrodeposition method for recovering rare earth elements from coal ash waste.

Previously, Dr. Choi has served as regional technology leader for desalination (US East) at CH2M HILL. He was also the director of research and development at Doosan Hydro Technology, in addition to serving as editor-in-chief of Membrane Water Treatment and journal reviewer for Water Research and Environmental Engineering Science.

Dr. Choi has participated in concept design, pilot study, troubleshooting, and cost analysis for some of the largest desalination and wastewater treatment plants in the world. He is a member of the International Desalination Association, International Water Association, Water Environment Federation, American Water Works Association, and American Membrane Technology Association.
