Dr. Dominic DiGiulio is a senior research scientist at PSE Healthy Energy. Dr. DiGiulio is also a visiting scholar in the Department of Earth System Science at Stanford University. Dr. DiGiulio completed a B.S. in environmental engineering at Temple University, an MS in environmental science at Drexel University, and a PhD in soil, water, and environmental science at the University of Arizona.
During his 31 years with the U.S. Environmental Protection Agency’s Office of Research and Development, Dr. DiGiulio conducted research on gas flow-based subsurface remediation (soil vacuum extraction), soil-gas sampling methodology, gas permeability testing, intrusion of subsurface vapors into indoor air (vapor intrusion), subsurface stray gas (methane and carbon dioxide) migration, and solute transport of contaminants in soil and groundwater including that associated with hydraulic fracturing. He assisted in development of guidance of EPA’s original guidance on vapor intrusion and the EPA Class VI rule on geologic sequestration of carbon dioxide. The focus of Dr. DiGiulio’s current work is on human health, environmental, and greenhouse gas emission aspects of oil and gas development in the United States and abroad.
