Ginnie is a stable isotope geochemist whose work focuses on environmental change and biogeochemical cycling. This involves the use of biological proxies to reconstruct past environments, as a means to disentangle the effects of natural versus anthropogenic climate change. In more recent years her work has looked into understanding, in more detail, contemporary controls on fluxes of nutrients in freshwater and marine environments and the impact that climate has upon these systems.

Current Research

Ginnie is a stable isotope geochemist whose work focuses on nutrient cycling and environmental change. Her work centers on modeling modern nutrient cycling (silicon, carbon) and primary productivity (diatoms) in freshwater and marine environments. Her more recent research highlights the vital importance that silicon cycling has to constrain global carbon cycling, with a view to mitigating future climate change. Ginnie works very closely with the British Geological Survey of which she is a Visiting Research Associate and her work falls under the umbrella of the Centre for Environmental Geochemistry.
