My research centres on how to monitor penguins and other marine predators in difficult environments such as Antarctica. Many of the most important environments on the planet are too data deficient to understand global change and to permit effective management. I spend a lot of time developing tools and techniques to scale up monitoring and data gathering from these environments.

Population Genetics of penguins
I am carrying out population genetic and phylogeographic studies of penguins around Antarctica and the sub-Antarctic, using SNPsand sequence data. The aim of this project is to see how different species of penguin populations are structured around the Southern Ocean and how these populations have changed in the past in response to changing ice conditions.

Many of the most important environments on the planet are too data deficient to understand global change, direct human impact and to permit effective management. I spend a lot of time developing tools and techniques to scale up monitoring and data gathering from these environments.

Cameras, counts and citizen science

Monitoring animals in such an extreme climate is challenging. Many species spend much of their time at sea, and the environment they live in is both hostile and remote, making the visits required to monitor them, demanding and costly. For these reasons, the monitoring efforts for many penguin colonies in Antarctica and the Sub-Antarctic islands have to date, been limited. However, by adapting existing camera technology and using time-lapse photography, we are trialling the development of a new monitoring array for the southern polar region.

You can see and participate in this research at www.penguinwatch.org

By monitoring remotely, we hope to be able to ask new questions about the response of Antarctic penguins to their changing world. By collaborating with tour operators we are trying to reach many more potential monitoring sites over the Antarctic Peninsula and surrounding islands. It is possible to expand the current limited monitoring network to include a far greater coverage of species and network sites, in a cost effective manner.
