Paul Dahlen is an assistant professor of research in civil and environmental engineering in the School of Sustainable Engineering and the Built Environment at Arizona State University. He received a bachelor's degree in hydrology from the University of Arizona, a master's degree and doctorate in civil and environmental engineering from Arizona State University, and has spent more than seven years working in industry as a hydrologist/environmental engineer. Dahlen's general research involves the assessment and remediation of hydrocarbon impacts to soil and groundwater. Specific research interests have included leaking underground storage tank impacts to groundwater resources, hydrocarbon vapor intrusion processes, oxygen injection technologies for use in in-situ permeable reactive barriers and soil remediation, the use of in-situ thermal remedial applications for hydrocarbon impacted soils and groundwater, and the management of crude oil impacts to the environment.
