Our lab aims to understand how aquatic macroinvertebrates process and transfer energy and cycle material in streams and wetlands. Our research quantifies how macroinvertebrate communities and their functions change in response to human activities to inform whole-ecosystem anthropogenic alterations. Our current research focuses on how watershed fragmentation, over-consumption​ of freshwater and contamination from agriculture, urbanization, and hydraulic fracturing interact to alter community structure and ecosystem functions in streams.

​We study macroinvertebrates because they
​

- are diverse and sensitive to changes in the environment.
- are important food for other organisms.
- recycle nutrients that are used by other organisms.

​
Current projects include research on how:
  • rapid land use changes, such as natural gas extraction and urbanization,
    alter associated freshwater ecosystems. 
  • low-level salt concentrations modify detrital pathways.
  • interactions among common and emerging watershed activities change stream structure and functions (for example, decomposition).
  • forest insect outbreak species alter stream food webs.
  • mining-induced salinization affects macroinvertebrate community structure and function in headwater streams
  • macroinvertebrates respond following recovery from acid deposition in streams of Shenandoah National Park.
