Biogeochemistry, hydrology, wetlands, riparian buffer zones and streams.
My research examines the interactions between biogeochemistry and hydrology that regulate stream chemistry in temperate landscapes. I focus on analyzing the role of the near-stream (riparian) zone and the hyporheic zone (the zone of stream water and subsurface water mixing in stream beds) in regulating the biogeochemistry of nitrogen and other mineral elements in agricultural and forested watersheds.
