Dr. Chunming Su
Dr. Chunming Su is a Soil Scientist in GWERD’s Subsurface Remediation Branch. He serves as a National Remedy Review Board member for Superfund sites cleanup. He is an author of more than 50 peer-reviewed journal articles and book chapters and a co-recipient of a U.S. patent. He has served as a reviewer for 50 scientific journals including Environmental Science & Technology, Geochimica et Cosmochimica Acta, Chemistry of Materials, The Journal of Physical Chemistry, and Soil Science Society of America Journal; and a reviewer of proposals to the Department of Commerce, EPA, U.S. Department of Agriculture, and U.S. Geological Survey. He has received several EPA Scientific and Technological Achievement Awards and EPA ORD Honor Awards. He has served as a mentor to dozens of National Research Council Resident Research Associates (regular and senior university faculty fellows), McNair Scholars, and Environmental Research Apprentice Program students.
Dr. Su’s research areas are nanotechnology and in situ chemical reduction. He conducts laboratory and field investigations in environmental geochemistry and nanotechnology. His research focus is on:
- Applications and implications of environmental nanotechnology with respect to the fate and transport of nanomaterials in the subsurface
- In situ treatment of organic (chlorinated solvents) and inorganic (chromate, arsenic, nitrate, etc.) contaminants in groundwater and soils using permeable reactive barrier technologies and monitored natural attenuation approaches
Dr. Su holds a Ph.D. in Soil Science from Washington State University in Pullman, Washington; an M.S. in Soil Science from the University of Guelph, Guelph, Ontario, Canada; and a B.S. in Soil Science and Agrochemistry from China Agricultural University, Beijing, China. Before joining the EPA, he worked as a project scientist with ManTech Environmental Research Services Corporation, Ada, Oklahoma; as a National Research Council Resident Research Associate, Ada, Oklahoma; and a term soil scientist for USDA, Riverside, California.
