Our faculty are a unique blend of researchers, educators and professionals who are proven experts in their fields.

Carolyn Butts-Wilmsmeyer , Associate Professor and Director of the Center for Predictive Analytics

Environmental Resources and Policy - Biological Sciences

Research Interests:

As a statistical geneticist, my research interests lie at the intersection of predictive models, plant genetics, and human health. The overall goal of my research program is to build statistical models that allow us to predict and improve plant characteristics of economic and societal importance, such as the nutritional quality of grain crops and the natural resilience of plant production systems. My current research projects include developing more predictive genomic selection techniques for complex traits and minimizing the occurrence of mycotoxin-producing fungal pathogens in grain production systems.

Nicholas Guehlstorf, Professor

Environmental Resources and Policy - SIUE Cooperative Faculty

I'm an environmental scientist interested in human health hazard and exposure assessment. My prior research experience largely focused on monitoring and modeling contaminant fate, bioaccumulation, and human exposure. I have also maintained an interest in environmental statistics and data analysis applications, as well as information exchange, collaboration, and education with other environmental specialists and the general public.

Kyong Sup Yoon, Assistant Professor

Environmental Resources and Policy - SIUE Cooperative Faculty

My main research interests span a spectrum of environmental toxicology and medical entomology to protect agriculture, animal and human health in environmentally safe, sustainable and affordable ways. I have been particularly interested in the following areas of interdisciplinary research: (1) mechanism of acute action of toxic substances: (2) genetic and epigenetic factors and processes associated with insecticide resistance; (3) adverse effects of sub-lethal and long-term exposure to environmental chemicals; (4) controlling and management of human head and body louse populations; and (5) developing and evaluating biochemical and molecular diagnostics for chemical and pest management. Overall, my scholarly work has attempted to addresses the linkage and interaction between exposure to environmentally ubiquitous toxic substances and factors governing physiology, genetics and epigenetics.
