My research interests are twofold, the Hydropedology of Vernal Pools and the use of Constructed Wetlands for Treatment and Reuse of Water. The vernal pool study is part of a Multi-State project with 8 other universities across the U.S., but predominantly in the northeastern states. The treatment wetland interests currently include a small wetland treating the water used to wash the turf equipment used at the Joseph Trool Research Plots in Deerfield, MA.
