Bio
Dr. Call is an Associate Professor in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University. Dr. Call is interested in biological and electrochemical processes to treat water and wastewater and recover resources from wastes. 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, CE 378 Environmental Chemistry and Microbiology, and CE 573 Biological Principles of Environmental Engineering at NC State.
Dr. Call’s research focuses on technologies that recover resources from wastes and generate new resources using lower carbon footprints than conventional approaches. He has expertise in both biological and electrochemical principles. Examples of current research interests include: (1) “rewiring” anaerobic digestion to produce high-value chemicals, (2) developing hybrid microbial-material interfaces that quickly and thoroughly transform aqueous contaminants, (3) desalination of brackish water using capacitive deionization (CDI), (4) improving phosphorus removal from wastewater using biological approaches, (5) using electrochemical approaches to remove and recover carbon dioxide and metals from aqueous sources, and (6) conversion of nitrogen gas into ammonium using microbial electrochemical technologies.
