Environmental Resources and Policy Faculty

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

Marjorie Brooks, Associate Professor

Environmental Resources and Policy - Zoology

I am interested in testing how multiple human stressors affect aquatic communities, and how we can alleviate those stressors so organisms and ecosystems can adapt to climate change. I also investigate the some fundamental aspects of the biogeochemistry of microbial communities meaning that I study a variety of aquatic systems in the lab and field

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.

Sylvia Smith, Professor

Dr. Sylvia Smith joined the faculty at SIU in 2007. She earned her doctoral degree from the University of Tennessee while completing research on Culinary Tourism. Her interest in food is what landed her in Carbondale, Illinois. During one of her interviews, she had a chance to visit the local farmer’s market. The market, people, and produce were so abundant and thriving she recognized the quality of life that could be possible in the Carbondale community. In 2010, she helped establish the Illinois Farmers Market Association.

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.
