Research Interests:

I am a stream community and ecosystem ecologist and much of my research is at the interface of these two ecological levels.  One major area of my research examines the roles of animals in organic matter and nutrient dynamics in stream ecosystems.  I am also interested in how anthropogenic factors such as pollutants may alter species functional roles by modifying organismal physiology and behavior.  My studies often employ ecological stoichiometry, which is the study of mass balance of multiple chemical elements in ecological interactions, as a tool to examine the functional roles of species in ecosystems.  Another area of my research focuses on the consequences of human-induced environmental change on stream communities and ecosystem processes.  I am currently examining thresholds in aquatic biodiversity across water quality gradients in streams to help guide the establishment of water quality criteria for EPA region VII.  I am also studying landscape controls on algal nutrient limitation and primary production in Central Plain’s streams.
