Chen has an extensive research interests in environmental science and engineering. More specifically, he is a leading researcher in the environmental applications of nanomaterials and their potential fate, transport, transformation, bioaccumulation and toxicity in the environment. His interests in environmental nanomaterials dated back in his graduate research in 1992. He has also been active on algae based bio-renewable energy and sustainable urban development. Chen has been principle and co-principal investigators for 28 research projects (by June 2010) funded by the National Science Foundation, U.S. Environmental Protection Agency, NASA, Boeing and other organizations. The total funds are $7 million. He has also served as a review member or panel review member in the U.S. National Science Foundation, the U.S. Environmental Protection Agency, the U.S. Department of Energy evaluation committee. He has also been invited to serve as an abroad review expert for the China Changjiang Scholars Program (which is to awarded to the top researchers in China). He has published more than 40 papers and two book chapters in this field.

Chen received his Ph.D in Nankai University, China. He joined the Georgia Tech School of Civil and Environmental Engineering in May 2009.

Ching-Hua Huang, Ph.D., is the Turnipseed Family Chair and Professor in the School of Civil and Environmental Engineering at Georgia Institute of Technology. Huang received her Ph.D. and M.S. degrees in environmental engineering from Johns Hopkins University. Huang’s expertise includes environmental chemistry, advanced water/wastewater treatment technology, contaminants of emerging concern, sustainable water reuse, waste remediation and resource recovery. Huang has supervised many research projects sponsored by various agencies, and has published more than 170 peer-reviewed journal papers, book chapters and conference proceeding papers. She is the Associate Editor of the American Chemical Society's Environmental Science & Technology Water and the Editorial Advisory Board member of Environmental Science & Technology.
