I am ecologist with a particular interest in the fields of behaviour and conservation. Much of my work is field-based, and centres around topics such as: how anthropogenic changes impact on movement, foraging and population dynamics; the causes and consequences of individual specialisation; the multifaceted impacts of invasive species; conservation of a range of avian species. I am fortunate enough to study these questions in a range of wild vertebrate systems.

I have a long-standing interest in island ecology, where study can address a wide variety of broad ecological and applied questions in both terrestrial and marine environments. These include the effects of human-mediated disruption through both the introduction of invasive organisms and subsequent attempts to control such species; restoration of endangered species through to entire ecosystems; the consequences of individual variation; and the role of birds as ecosystem drivers.
