My major field of study is microbial ecology. Basic, molecular biology and “omic” techniques are used to gain a better understanding of the adaptation of environmental microorganisms to perturbed ecosystems. Microbial analyses range from examination of the entire community to the identification specific bacteria and genes responsible for the underlying functions. Perturbed ecosystems being studied are human/animal guts, metal and/or hydrocarbon contaminated sites, wastewater treatment facilities, stream and lake water exposed to urban and rural inputs, and agricultural fields subjected to different agronomic practices (see examples in select publications below). Ultimately with this research we hope to determine different mechanisms involved in bacterial adaptation to the environment and identify factors that contribute to community composition.

CURRENT TEACHING RESPONSIBILITIES
AGRY349- Soil Ecology (taught 1999-2006, 2020-present, lecture and laboratory). This course covers the basic concepts of soil ecology. The lectures include interactions between and within both biotic and abiotic components of the soil ecosystem. The major topics covered in the class are: 1. nutrient cycling; 2. biological diversity and interactions; and 3. importance of soil ecology in optimizing soil productivity (e.g., for soil health)
AGRY649- Molecular Microbial Ecology (taught yearly since 1996). The course focuses on both the theoretical and practical applications of various molecular genetic techniques used to study microorganisms from and in the environment. The major areas discussed are the application of molecular genetic techniques to study: 1) total microbial communities; 2) diversity of microorganisms in a community; and 3) biotechnological uses of microorganisms. The course is taught in a manner for students to develop independent skills for obtaing new knowledge, critical thinking and communication.
