Research Interests:
My overall research programs cover the movement, disposition and ultimate degradation/fate and toxicity of chemicals in environmental matrices (water, sediment and biota) with a focus on Louisiana watersheds, wetlands and coastal areas. We develop laboratory and field methods to assess important biological and physical dissipation processes in surface soils/sediments as well as near surface water and measuring contributions of chemical loads by different use patterns to non-target freshwater and marine watersheds. We have programs assessing the transport of pesticides, petrochemicals, and human health pharmaceuticals and their degradation products in soil and water, the influence of sunlight on their degradation and toxicity in soil and water, environmental and biological processes influencing pesticide and pharmaceutical degradation, and the environmental impact of pesticides and pharmaceutical products. We also have projects assessing amounts of chemical contamination in manufactured and retail food and animal feed and the impacts on human health. There is a strong emphasis on research as it impacts regulatory science in ecological and human health risk assessment such that the best available science is incorporated into regulatory and policy decisions at the state, national and international levels.

Thomas DouthatThomas Douthat
Assistant Professor

tdouthat1@lsu.edu 
2111 Energy, Coast and Environment Building
Research Interests:
I study how place based systems adapt to social, economic, and environmental change through the lenses of law, planning and policy, and economic geography. My work has involved diverse subjects ranging from coffee to transportation, and spans both rural and urban areas. I approach problems through the prism of my background in the fields of environmental planning and governance, spatial analysis, and law, and seek to create practical solutions for a more equitable and resilient society. This involves adaptation in socio-environmental systems (e.g. coastal communities, and agriculture), linkages between environmental and economic systems, and sustainable transportation.

Crystal JohnsonCrystal N. Johnson
Associate Professor

cnjohnson@lsu.edu 
2283 Energy, Coast and Environment Building
Research Interests:
I am currently examining how Vibrio spp. (V. parahaemolyticus, V. vulnificus, and V. cholerae) respond to environmental cues, including sea surface temperature, salinity, chlorophyll, turbidity, suspended particulate matter, and dissolved organic carbon. It is well-established that temperature affects the levels of these naturally occurring marine bacteria (i.e., their levels are higher in warmer months and lower in cooler months), but it remains unclear what combinations of other environmental factors contribute to the variations in vibrio levels.

yonghakim1@lsu.edu 
1261 Energy, Coast and Environment Building
Research Interests:
With the goal of developing new principles and technologies that can improve the quality of human life and lead to sustainable development, my research is focused on the fundamentals of colloid and surface science and radiation chemistry and physics, and their applications in environmental engineering and science. My current research interests include colloidal phenomena and contaminant transport modeling in environmental systems, radiation dosimetry and indoor air quality, and chemical and environmental process intensification.
