Teaching Interests
I teach courses in general microbiology, microbial ecology, and brewing methods. In microbiology I focus on individual bacterial species within particular environments such as soil, water, and plant and animal hosts. In lab, students work within a specific habitat, e.g., soil from the Smokies, campus streams, or decomposing humans. In microbial ecology, I show interrelationships to other microorganisms and the labs explore a specific habitat. My brewing course focuses on yeast and how they produce fermented products such as beer, cider, and mead. Students learn how to make these products and how to assess their creations and improve their processes.
Research Interests
My research interests are tied to the diversity of microbial life. I have worked in Great Smoky Mountains National Park since my first year at WCU. My students and I have explored the diversity of bacteria in soils, waters, caves, and elk and hemlock hosts. We try to understand the extent of species diversity in these environments and how species interact. More recently our work has expanded to include fungi and nematodes from the same habitats. I also have worked with students at WCU’s FOREST facility to understand microbial dynamics during decomposition as a tool for forensic analyses.
