Research Interests

The area of science that excites me most is figuring out new and useful ways of analysing ecological data to discover more about animals, particularly marine animals, and how they go about their lives and are successful in persisting in a dynamically changing world. More specifically, my main interest is animal movement ecology. I’m interested in how animals distribute themselves in space, navigate, forage and interact with physical features of the environment.

For my PhD I worked on diving behaviour and ecology of seals, using data collected remotely using animal-attached instruments. These data make it possible to study the lives of free-ranging animals but also pose considerable challenges, specific to the remote collection and transmission of data. I still have strong collaborative links with colleagues at the University of St Andrews, and Glasgow University with whom I work on movement modelling of marine mammals, mainly seals.

At UCT I have worked primarily on developing state-space and Hidden Markov models for raptor movement data, and I am collaborating with people from the Animal Demography Unit.

I also have various little side projects I work on from time to time, that do not relate to movement ecology. For example, I have been collaborating with Philip Ebert, from the Philosophy Department at the University of Stirling, Scotland, on the perception of risk under uncertainty.
