Our group is working on several projects at the Hubbard Brook Experimental Forest in New Hampshire. These projects have been funded by a variety of sources including NSF Hydrologic Sciences, NSF LTER, NSF DBI-REU, USDA Forest Service Northern Research Station, and Plymouth State University.
- Landform controls on hydrologic flowpaths and pedogenesis explain solute retention and export from pedon to catchment scales.
- Collaborators: Scott Bailey (USFS), Tom Bullen (USGS), Don Ross (UVM)
- Graduate Students: Rebecca Bourgault (Ph.D., UVM), JP Gannon (Ph.D., VT), Cody Gillin (M.S., VT)
- REU Students: Patricia Brousseau (B.S., UVM), Tyler Kreider (B.S., SUNY-ESF), Maggie Zimmer (Oberlin College), Katie Harvey (U. Kentucky), Maggie Burns (U. Maine, now at UC-Boulder), Bridget O’Neill (Pitt now at U Del), Russell Callahan (Montana State), Kelly Floro (Geroge Mason), Cailene Gunn (Bates)
Runoff generation processes

Spatial patterns in valley-wide stream chemistry
- Linking network patterns and processes of streamwater chemistry across scales in Hubbard Brook Valley.
- Collaborators: Christian Torgersen (USGS), Gene Likens (Cary Institute for Ecosystem Studies), Don Buso (Cary Institute), Winsor Lowe (Montana), Scott Bailey (USFS)
