Nicholas Guehlstorf, Ph.D. (Purdue), Associate Professor
Dr. Nicholas Guehlstorf’s research focuses on the integration of democratic values into environmental policy and considers the theoretical problems with citizen involvement, economic development, and scientific information in decision making. Dr. Guehlstorf currently offers courses in environmental law, American government, political theory and environmental public policy and administration.
Kevin Johnson, Ph.D. (Clemson), Professor
Dr. Johnson’s current research interests include: Development of a novel extraction techniques for some persistent organic pollutants (POPs) in turtle blood along the Tennessee River over a five year period and with five different species; Use of turtle blood as a biomonitoring technique for pharmaceuticals, personal care products and endocrine disrupting compounds (PPCP & EDC) and POPs along the Illinois River; PPPCP, EDCs and some in water samples, such as determining their: levels, removal strategies, and toxicity; levels in surface waters along the Illinois River; removal efficiencies in three different waste water processing treatments; aquatic toxicity testing of individual, and mixtures thereof, PPCP, EDCs, & POPs found in both of the above studies; and lastly insecticide exposure analysis in wildlife (and their prey items).
Zhi-Qing Lin, Ph.D. (McGill), Associate Professor
Dr. Lin’s research interests include (1) developing phytoremediation technology for the cleanup of trace element contaminated water and soil, including the use of phytoextraction, phytostabilization, phytovolatilization, and constructed treatment wetland systems; 2) understanding the control of major environmental factors over the biogeochemical cycles of environmentally important trace elements in the air-water-soil-plant system, particularly with respect to transport, fate, and chemical transformation of pollutants in ecosystems; 3) characterizing ecosystem responses to phytoremediation processes and other anthropogenic perturbations, such as agricultural or industrial pollution and waste management.
William Retzlaff, Ph.D. (Clemson), Professor
Dr. Retzlaff is interested in the performance of green roof and living wall technologies in the Midwestern United States. He and his collaborators and student conduct experiments on the performance of green roof and living wall technologies and make the research information available to users for development / establishment of green roof and living wall systems.
Chris Theodorakis, Ph.D. (Tennessee), Associate Professor
Dr. Theodorakis’s research interests are in evolutionary toxicology, nanotoxicology, molecular and genetic toxicology, aquatic ecotoxicology, population genetics, biomarker research, oxidative stress, and endocrine disruption. Current research projects include: 1) effects of metal and metal oxide nanoparticles on fish, amphibians, and bacteria, 2) effects of thyroid hormone disruption on arsenite-induced oxidative stress and DNA damage, 3) oxidative stress biomarkers and conservation genetics of gopher tortoises, 4) population genetics of Mediterranean mussels from the Strait of Istanbul, and 5) effects of nitrogen and phosphorous inputs on water quality in local lakes and ponds.
Melissa (Pui Ling) Chan, Dr. Engineering (Kyoto, Japan), Assistant Professor
Dr. Chan’s research interests are (1) development of a mathematical and engineering framework to evaluate human health risks in the context of "Systems Environmental Health", (2) evaluation of tools and models used for quantitative extrapolation of in vitro to in vivo data, (3) toxic effects of chemicals/endocrine disrupting chemicals in the neuronal system.
