Year Joined Homerton: 

The aim of my research is to broaden our understanding of how climate change affects the Arctic marine ecosystem and associated communities in terms of species composition, richness and interactions. I further study the impacts of invasive species on Arctic ecosystems and I use blue mussels, which are excellent harbingers of the effects of future climate change, from Greenland, Iceland, Svalbard, Russia and Denmark to investigate how physiological adaption to the Arctic environment translate into defining distribution limits, abundance patterns and potential range shift of invasive species.

Research Interests: 

Arctic ecology, Climate change, Animal physiology
