Research Interests
My primary research interests are in basic aquatic
ecology and ecotoxicology. My research has focused primarily on understanding
how benthic macroinvertebrate communities respond to natural and anthropogenic
stressors. By integrating biomonitoring studies with field and microcosm
experiments, my students and I have attempted to understand the basic ecological
effects of contaminants on aquatic communities. More recently, our research
projects have included assessments of recovery from fire disturbance, quantifying
interactions between natural and anthropogenic stressors, and measuring abiotic
factors that influence contaminant bioavailability.
The primary sources of funding for our research have been the U.S. Environmental Protection Agency, the National Institute of Environmental Health Sciences, the Colorado Division of Wildlife, the U.S. Forest Service, the U.S. Geological Survey, and the U.S. Park Service.

Courses Taught
I teach three primary courses. In alternate years
I teach Ecology (BY 320), a required course for all undergraduate students
in the department. Each year I teach Design of Wildlife Projects (FW 370),
a required course that introduces students to the research process. Topics
range from the philosophy of science to experimental design and scientific
writing. Each spring semester I teach a graduate course in Ecotoxicology (FW
544). This course examines the ecological effects of contaminants on populations,
communities, and ecosystems.
