My Research Interests: (Environmental Biology, Aquatic Ecology)
Research focuses on aquatic community responses to stress; development and testing of biological monitoring and assessment techniques; ecological characteristics of aquatic communities and relationships to landscape features; studies of ecological interactions across the land-water interface; utilization and assessment of environmental education programs in public schools.

Courses I Teach:
Principles of Ecology (Biol 311) - provides an introduction to basic concepts in ecology; influence of abiotic factors on individual organisms, populations, communities and ecosystems; population dynamics and life-history strategies; competition, herbivory, predation and symbiotic relationships; disturbance and succession; community structure and function; ecosystem energetics and biogeochemical cycling; abiotic and biotic attributes of major ecosystems; use of scientific method to investigate ecological issues in field settings. To see a copy of the most recent syllabus, click here.
Principles of Ecology Laboratory (Biol 311L) - Ecological problems are addressed using a variety of field and laboratory equipment and protocols. The objectives of this course are to (1) develop a familiarity with commonly used equipment used to collect ecological data, (2) use the scientific method to investigate ecological questions in terrestrial and aquatic environments, (3) perform basic analyses on ecological data and (4) apply the principles of scientific writing to communicate study results. This course is offered as a laboratory series enhanced with technology. Course material is developed at a level suitable for juniors and seniors.

Disturbance Ecology (EnvM 425/525) - provides an introduction to concepts, techniques and applications of biological monitoring for environmental management; study of impacts to ecosystems from natural and human caused events; application of ecological principles to natural resource issues; laboratory and field exercises used to demonstrate monitoring and assessment techniques to detect the influence of disturbance at different levels of biological organization (cell to ecosystem).
