| Heileen Hsu-Kim, Professor in the Department of Civil and Environmental Engineering and Pratt School of Engineering
Professor Heileen (Helen) Hsu-Kim's research interests include the chemical processes that affect the fate of trace metals in the environment. In particular, she is interested in the biogeochemical cycling of pollutant metals and interfacial processes controlling the fate and bioavilability of nanoparticles in aqueous systems.
Dr. Hsu-Kim's current research efforts focus on the role of reduced sulfur and natural organic matter for controlling mobility and toxicity of metals in the aquatic environment. The methodologies her group employs for this research include laboratory techniques for quantifying trace metal speciation, water-surface interactions, and in-situ applications of solid-state microelectrodes to determine important aquatic constituents in water and sediment.
