People

Research in our lab is dedicated to understanding how anthropogenic activities alter community structure and ecosystem processes (e.g., productivity, decomposition, and biogeochemical cycling) in freshwater ecosystems. Much of our research has focused on the impacts of consumers on basal food resources, community structure, and nutrient dynamics in streams and wetlands. We attempt to view our work through a social-ecological lens, acknowledging the powerful impacts that public policy and economic considerations can have on the quality and quantity of freshwater resources, the abundance and diversity of aquatic organisms, and the function of freshwater ecosystems. In an attempt to translate scientific knowledge to actionable outcomes, we actively work with community groups and local, state, and federal employees to develop programs that integrate stakeholder concerns into our research planning. Integrating a diverse set of perspectives into our work is important to develop a more comprehensive understanding of freshwater science. We embrace our lab members’ differences in gender, color, disability, ethnicity, age, family or marital status, gender identity or expression, language, national origin, ability, political affiliation, race, religion, sexual orientation, socioeconomic status, veteran status, and other characteristics.
