We work primarily with native stream fish assemblages, including rare species, from the mid-Atlantic to New England region. Our work is currently confined to small (0-5 order) rivers and we focus on smaller non-game species that are important hosts for freshwater mussels such as the Percidae (perch and darters), Catostomidae (suckers), Cyprinidae (dace and minnows), Cottidae (sculpins), Centrarchidae (sunfishes), Ictaluridae (bullhead catfishes), Salmonidae (primarily native brook trout), and American eel.

• Single-species or community surveys in wadeable streams using one or more sampling techniques: electrofishing, nets, seines, traps, snorkeling, or SCUBA diving.
• Threatened and endangered fish surveys and habitat assessments
• Fish and mussel studies: host suitability, host availability, ecological interactions
  Fish surveys and monitoring associated with stream barrier (culvert or small dam) repair, removal, or replacement projects
• Fish habitat analysis, mapping, and modeling for a variety of applications (instream flow studies, physical habitat alteration, stream restoration, barrier removals, stream crossing structures)
  Fish biomonitoring and community analysis using state or federal rapid bioassessment protocols, comparison to Target Fish Community (TFC), and implementation of Fish Index of Biotic Integrity (IBI)

• Fish biomonitoring in streams in the Taunton River watershed of eastern Massachusetts
  Monitoring fish community changes in response to dam removals in Pennsylvania
• Evaluation of occurrence and distribution of potential fish hosts for eastern elliptio (Elliptio complanata) in the Susquehanna River basin in Maryland, Pennsylvania and New York
  Assessment of potential fish hosts for dwarf wedgemussel in the Delaware and Connecticut River basins
