Research summary

Pierre Regnier's research focuses on global carbon and nutrient cycles and their anthropogenic perturbation with a strong emphasis on inland waters, estuaries, coastal environments and the seafloor and their interaction with terrestrial ecosystems and the open ocean. His expertise encompasses the biogeochemistry of carbon and nutrients, carbon dioxide, methane and nitrous oxide cycling, model-data fusion approaches and advanced statistical methods, reactive-transport modelling and Earth system science.
