Dr. David O'Connell

Assistant Professor (Civil Struct & Env. Eng.)

 


Assistant Professor in Environmental Systems Engineering with a focus on engineered and nature-based solutions for environmental pollutants and mitigation, sustainable engineering and resource recovery, engineered solutions for sustainable food production, natural system processes understanding and management in the Department of Civil, Structural & Environmental Engineering. My research expertise covers contaminant hydrology and hydrogeological processes for water resources, groundwater and surface water, pollutant tracing and wastewater treatment technologies. Furthermore, I have advanced skills in studying earth systems processes governing water quality across scales from the catchment scale to nanoscale using multiple chemical and solid-state techniques. I have additional skills in design and development of nature based solutions coupled with water purification materials and systems. Recently my research has moved into the area of sustainable agriculture with a particular focus on water quality and quantity protection along with nutrient recovery.
