Department of Earth Sciences

 

I am a PhD candidate in the Department of Earth Sciences, University of Cambridge and the Biodiversity, Evolution and Adaptation team at the British Antarctic Survey. My research involves investigating the effects of osmotic stress on marine animals, with a focus on the resistance of Antarctic marine species to predicted freshening and lower salinity in the Southern Ocean as a result of climate change.

Interests:

  • Animal physiology
  • Phylogenetics
  • Genetics
  • Evolution and biodiversity
