Dr. Chunming Su
Dr. Su is a Soil Scientist in GWERD’s Subsurface Remediation Branch. He is a principal author of more than 30 peer-reviewed journal articles and book chapters and a co-recipient of a U.S. patent. He has served as a reviewer for 32 scientific journals, including Environmental Science and Technology, Geochimica et Cosmochimica Acta, Chemistry of Materials, 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 (USDA), and the U.S. Geological Survey.
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 in Guelph, Ontario, Canada; and a B.S. in Soil Science and Agrochemistry from China Agricultural University in Beijing, China. Before coming to EPA, he worked as a project scientist with ManTech Environmental Research Services Corporation in Ada, Oklahoma; as a resident research associate for the National Research Council in Ada; and a term soil scientist for USDA in Riverside, California.
