Young-Shin Jun leads the Environmental NanoChemistry Laboratory at Washington University in St. Louis. She earned her BS (1997) and MS (1999) in Environmental Science and Engineering at Ewha Womans University in Seoul, Korea. She holds an SM and earned a PhD in Environmental Chemistry from Harvard University in 2005. Prior to taking her position at Washington University, she conducted postdoctoral research in Nanogeoscience at the University of California at Berkeley/Lawrence Berkeley National Laboratory, Berkeley (2005-2007). Professor Jun is a 2011 U.S. National Science Foundation CAREER award recipient. Her research focuses on environmental interfacial reactions in dynamic, complex aqueous systems. Her research group’s projects aim at providing more environmentally sustainable CO2 sequestration strategies, improving our understanding of the fate and transport of nanoparticles and contaminants, and elucidating physicochemical reaction mechanisms occurring during water reuse through aquifer storage, treatment, and recovery to secure underground sources for drinking water. She is on the Editorial Board of the Royal Society of Chemistry’s Environmental Science: Processes & Impacts. She also served as the lead guest editor of a 2013 special issue on geologic CO2 sequestration of the Environmental Science & Technology.
