Interests
Dr. Liljestrand's research interests are in environmental chemistry, in the air, aquatic systems, and hazardous materials. His current research activities are related to modeling of chemical conversion and transport processes in environmental systems. His most current research interests involve studies of the organic pollutants, especially endocrine disrupting compounds. Other recent work has involved transport and transformation processes in the vadose zone and remediation of aquifers with foams. His air pollution work has included modeling of particulate emissions from contaminated surface sites, structure-activity relationships for the kinetics of the photochemical oxidation of volatile organics by titanium dioxide photocatalysts, and source-receptor modeling of pollutants including chemical transformations during transport.
