Heileen Hsu-Kim

Professor in the Department of Civil and Environmental Engineering

Professor Heileen (Helen) Hsu-Kim is an environmental engineer who specializes in environmental aquatic chemistry and geochemistry. Her research tackles problems related to pollutant metals and the biogeochemical processes that alter their distribution in water, soil, and air. The applications of this work include environmental remediation technologies, the impacts of energy production on water resources, global environmental health, and the environmental implications and applications of nanotechnology.

Dr. Hsu-Kim's current research projects are focused on mercury biogeochemistry, the impacts of coal ash disposal on water quality, recovering valuable materials from geological wastes, and health impacts of trace metal/metalloid exposures. A central theme to her work is the utilization of chemical speciation for understanding and predicting the persistence, mobility and bioavailability of metals and minerals in the aquatic environment.

The methodologies her group employs for this research include laboratory techniques for quantifying trace element speciation, functional measures of reactivity and bioavailability of contaminant metals, and techniques to probe interactions at mineral, water and microbial interfaces.
