Dr. David William O'Connell
Assistant Professor, Civil Struct & Env. Eng.

Biography

Assistant Professor in Contaminant Hydrogeology and Hydrology in the Department of Civil, Structural & Environmental Engineering. My research focuses on water resources, water and wastewater treatment technologies along with studying earth systems processes governing water quality across scales from the field scale to nanoscale using multiple chemical and solid-state techniques. My expertise includes water resources, water and wastewater treatment technology, hydrogeology, hydrology and biogeochemistry with a focus on systems understanding and innovative solutions.

Research Expertise

Description

My principal research interests lie in the broad area of hydrogeology, biogeochemistry and hydrology associated with environmental engineering. My background covers water and wastewater treatment technologies along with studying earth systems processes governing water quality across scales from the field scale to microscale using multiple chemical and solid-state techniques. My research in hydrology and hydrogeology investigates groundwater flow rates, nutrient cycling and contaminant tracing to surface water ecosystems and aquifers (i.e. groundwater resources, lakes, rivers and springs) using multiple conventional and non-conventional methods such as stable isotopes, advanced spectroscopy, hydrochemistry and microbial techniques. Coupled with my work on hydrogeology and hydrology, I have worked in the area of nutrient biogeochemistry and eco-hydrology with a focus on nutrient cycling in lakes, wetlands, streams and rivers.
