I seek to advance ecology through research in the marine environment. The majority of my work to-date has concerned the limiting effects of competition and the environment on the spatial usage, foraging behaviour and population sizes of seabirds. My approach is to record animal movements and behaviour using biologging technology (satellite tags, activity and stomach temperature loggers, etc.) and to quantify oceanographic processes using remote-sensing. I am particularly interested in the spatial implications of colonial living and central-place foraging, not least because these are traits that seabirds share with a diverse array of animals, from bats to bumblebees. I am also involved in efforts to use tracking data for seabird conservation, for example by identifying potential offshore marine protected areas and assessing the impacts of offshore renewables developments.
