I am a biogeochemist with expertise in riverine and oceanic environments and a particular interest in the nitrogen cycle and associated biogeochemical cycles and how these will be affected by climate change. I utilise nitrogen isotopes to help understand the processes controlling nitrogen fixation and future changes to the marine nitrogen cycle in the North Atlantic and Mediterranean.
