Inland waters serve as critical conduits in the global carbon and nutrient cycles. The lab investigates how terrestrial elements, organic matter, and pollutants are transported and transformed within river networks. With both empirical and theoretical advances like the Pulse-Shunt Concept, this research challenges traditional views of riverine biogeochemistry, emphasizing the episodic and dynamic nature of elemental fluxes. This research integrates spatial analysis, isotopic tracers, organic geochemistry, and hydrological modeling. By coupling field observations with computational modeling, the team aims to refine predictions of carbon transport and its implications for global carbon budgets.
