Student research in my lab uses a combination of environmental monitoring, modeling approaches, and field experiments to advance understanding about the impacts of human activity on aquatic ecosystems. In particular, I am interested in the influences of long-term changes in watershed land use and pollution sources on surface water quality, the environmental factors that select for harmful phytoplankton species and invasive, non-native species, and the responses of various aquatic organisms to heavy metals and other environmental contaminants.

Representative studies:
•    Environmental characteristics and plankton dynamics of Raritan Bay, a eutrophic estuary. Danielle Sobol (’12) and Alyssa Calomeni (’11), Current Independent Research Project
•     Impact of differential zooplankton grazing on phytoplankton community composition in Raritan Bay.  Alyssa Calomeni (’11), Current Independent Research Project
•    Decomposition rate and phosphorus concentrations of purple loosestrife (Lythrum salicaria) in the Bushkill Creek watershed.  Jeff Hollander (’11), Current Independent Research Project
•    Assessing the quality and availability of GIS data for point and non-point sources of nutrients and pollutants in the Raritan River Basin.  Andrew Chun (’12), Future Independent Research Project
