Staff profile

I am a biogeoscientist with interests that encompass climate and environmental change in physical, geochemical and biological contexts. I have experience in palaeoclimate and palaeoenvironmental reconstruction, co-production of knowledge with indigenous communities, and in science communication and outreach. 

I am currently a Research Associate at Durham University, working on Arctic and Antarctic sea ice reconstruction within the Horizon Europe project Past to Future (P2F): towards fully paleo-informed future climate projections. I am undertaking data compilation and assessment of sea ice proxy records from marine sediment archives, and synthesis of such data into reconstructions and maps of past sea ice extent in the polar regions. Synthesised and newly generated data will feed into model-data integration within the wider P2F team. A better understanding of past sea ice states and stronger data-model integration are essential for improving our ability to anticipate the future trajectory of sea ice and its cascading effects on global climate.

I have also worked on the northward expansion of beavers in the Arctic, tundra plant ecophysiology, and Holocene sea ice reconstruction focused on utilising driftwood as a proxy for surface circulation dynamics.
