The main focus of the Biogeochemistry Group is to investigate major elemental cycles in streams and their watersheds, particularly carbon, nitrogen, and phosphorus pools and fluxes. We are especially interested in quantifying and characterizing the rich array of organic molecules that exist in stream ecosystems, and serve as the main food source to microorganisms and consequently to all biological communities. Throughout the watershed, water is found in many places beyond stream channels, including aquifers, soils, and sediments. Our biogeochemistry laboratory has the capabilities to perform a wide range of chemistry analyses in water samples from all these places.

Stream restorations rarely get monitored rigorously enough to determine if the “patient” has fully recovered.
We're studying how White Clay Creek can recover from deforestation and agricultural expansion and to what extent restoration practices can acclerate that recovery.
To truly make a difference requires, not only understanding freshwater systems, but working with all kinds of communities to protect them.
The COVID-19 pandemic prevented us from bringing interns onto our campus this year but we are fortunate to have four interns working remotely.
