I study biogeochemical cycles in lakes, estuaries and oceans, focusing on the elements of carbon, nitrogen, phosphorus, sulfur, and iron. I investigate how biogeochemical cycles respond to changing environmental conditions, coupling field and laboratory data with modeling. I aim to make projections across systems and scales and predict ecosystem’s responses to climate changes and anthropogenic perturbations.
