Dr. Liljestrand's research interests are in environmental chemistry, in the air, aquatic systems, and hazardous materials. His current research activities are related to measurements and modeling of chemical conversion and transport processes in environmental systems and tracing pollutant releases. Specific research projects involve studies of the interactions of organics with soil and clay minerals, the partitioning of endocrine disrupter chemicals between soluble, complexed, and particulate phases, coupling atmospheric chemical reaction rate with dry deposition processes, modeling of fugative emission fluxes of particulate pollutants, and source-receptor modeling of pollutants including chemical transformations during transport.
