Newton International Fellow

I am a quantitative ecologist with a background in marine and environmental biology and statistics. I am interested in the movement ecology of animals - mainly swimming, diving and flying animals. More generally, I like using statistical methods to learn about pattern and process in the ecology and biology of animals.

During my Newton International Fellowship at the University of St Andrews I will be looking at the effects of ocean properties on the movement ecology of Weddell seals under the project title EMEWS. There is a strong methods development and implementation focus for this project, particularly time series models for animal movement.

Research Overview:

I am a quantitative ecologist with a background in marine and environmental biology and statistics. I like using statistical methods to learn about pattern and process in the ecology and biology of animals in general, but my main interest is the movement ecology of animals – mainly flying, swimming and diving animals.

For my Newton International Fellowship I am working on adapting and developing methods for better understanding the diving ecology of a truly Antarctic, ice dependent species, the Weddell seal. Using statistical methods for information collected through time, I am looking at how diving behaviour changes over time in individual seals, and how that relates to the oceanographic features they are experiencing in the Weddell Sea, a part of the Southern Ocean that is regarded as a sentinel for climate change.
