Greg Lowry is the Walter J. Blenko, Sr. Professor of Civil and Environmental Engineering. He is deputy director of the NSF/EPA Center for Environmental Implications of Nanotechnology (CEINT), and on the editorial board for Environmental Science: Nano and Nature: Scientific Data. Lowry holds a B.S. in chemical engineering from the University of California at Davis, an M.S. in civil and environmental engineering from University of Wisconsin at Madison, and a Ph.D. in civil and environmental engineering from Stanford University.

His research focuses on environmental geochemistry, nanochemistry, and environmental nanotechnology. His current professional interests include applications of nanomaterials for sustainable agriculture, robotics for autonomous soil sampling and site characterization, environmental fate and transport of chemicals, groundwater remediation, and environmental issues related to fossil energy.

Lowry is a Fellow of the American Association for the Advancement of Science (AAAS). He has published over 150 scientific articles in leading environmental engineering and science journals, and a book on nanoscale iron particles for groundwater remediation. He has received awards for his research from the American Society of Civil Engineers (Walter L. Huber Civil Engineering Research Award), the Association of Environmental Engineering and Science Professors (Malcolm Pirnie/AEESP Frontiers in Research Award), and the American Chemical Society (Best Feature Article in Environmental Science &Technology for 2012). He received the Distinguished Service award from AEESP in 2018, and was awarded the Fenves Award for Systems Research in 2011. He is a “highly cited” scientist (top 1%) in the area of ecology and environment according to Thompson Reuters/Clarivate (2014-2018).

Lowry's research has been supported by the federal government (National Science Foundation, U.S. Department of Defense, U.S. Army Research Office, U.S. Department of Energy, and U.S. Environmental Protection Agency), with additional grant support from industry. Lowry has served on two NAS panels; Science Breakthroughs to Advance Food and Agricultural Research by 2030 and the Committee to Develop a Research Strategy for Environmental Health and Safety Aspects of Engineered Nanomaterials. He served as a science advisory board member for the international research Centers, NANOREM and NANOFASE.
