I am a Lecturer in Marine Science with strong research interests in polar ocean biogeochemistry and marine ecosystem change in both the Arctic and the Antarctic.

I am an investigator on two projects as part of the UK NERC Changing Arctic Ocean program, which aims to characterise and quantify the changes in marine biological productivity and biogeochemical cycling occurring in response to rapid warming and sea ice losses in the Arctic region.

  • Arctic PRIZE (PRoductivity in the seasonal Ice ZonE) is a multidisciplinary international project examining the effect of sea ice changes in the Arctic Ocean on ocean physics and nutrient dynamics and consequently on biological productivity and ecosystem functioning.

  • The Changing Arctic Ocean Seafloor (ChAOS) is a multidisciplinary project to elucidate the impacts of declining sea ice cover in the Arctic Ocean on the biological communities and nutrient cycling in seafloor ecosystems, and the implications for carbon sequestration and burial.

I also have research projects underway at the west Antarctic Peninsula examining carbon and nutrient dynamics and ecosystem change in response to large variability and change in sea ice cover. My NERC Independent Research Fellowship examined the marine nitrogen cycle in this region, its coupling with the biogeochemical cycles of carbon and other nutrients, and the interactions between ocean biogeochemistry, ecosystem functioning and climate change.
