Dr. Guehlstorf

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.

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.

Zhi-Qing Lin, Ph.D. (McGill), 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.

Adriana E. Martinez, Ph.D. (Oregon), Assistant Professor

Dr. Adriana E. Martinez's research focuses on the influence of human activities along river systems.  She most recently studied the interactions between invasive riparian vegetation and stream channels.  Vegetation influences river systems, through the interruption and channeling of flow, and is influenced by rivers, through the timing and regularity of inundation and nutrient fluxes. The resurgence of this science, biogeomorphology, is helping researchers better understand river systems and ultimately, helping us more efficiently and effectively restore rivers that have been significantly altered by human practices.

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.
