Douglas Call

Assistant Professor

Dr. Call is an Assistant Professor in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University. Dr. Call is interested in the development of efficient biological and electrochemical technologies to recover energy, nutrients, and high-value chemicals from unconventional and impaired water sources, such as wastewater and salinity gradients. Watch a short video below to hear Dr. Call briefly explain his research focus.

Dr. Call received both his MS (2008) and PhD (2011) in Environmental Engineering from Penn State University. He continued as a postdoctoral scientist at Penn State until becoming an Assistant Professor of Civil and Environmental Engineering at Syracuse University in 2012. He is currently teaching CE 373 Fundamentals of Environmental Engineering and CE 573 Biological Principles of Environmental Engineering at NC State.

Research Description

Dr. Call's research focuses on technologies at the interface of the water-energy nexus. In particular, he is interested in recovering resources, such as energy and nutrients, from wastewater. He combines his multidisciplinary background in microbiology, molecular biology, and electrochemistry to research hybrid bioelectrochemical technologies, such as microbial fuel cells, that convert liquid and gaseous wastes into energy and high-value products. Other research topics Dr. Call is working on include biological-based methane mitigation from engineered environments, methane generation in anaerobic systems, and salinity-gradient energy recovery.
