Research Focus:
Modeling of the Earth System:
- Carbon fluxes in high latitude terrestrial ecosystems
- Riverine nutrient and carbon transfer from land-to-ocean
- Multi-stressor anthropogenic perturbation of the coastal ocean across temporal and spatial scales
Research Interests:
My research interests focus on improving the modeling and understanding of the impacts of human-induced perturbations of the climate and ecosystems at the global and regional scale. Currently, I am working towards improving the understanding of nutrient availability on carbon fluxes in high latitude by improving the global model JSBACH and the process-focussed site-scale model QUINCY, to better represent nutrient fluxes associated with permafrost thawing. Previously, I have extended global models to better represent the riverine transfer of freshwater and biogeochemical compounds from land to the ocean, the perturbation of these fluxes due to human activities and their impacts on the coastal and open ocean.
