My main research and teaching interests are in the ecology and conservation of marine systems, with a particular focus on marine top predators. For over twenty years, my group’s research has focused on understanding how natural and anthropogenic environmental change influences the behaviour and dynamics of marine mammals and seabirds. This work has been underpinned by the development and maintenance of long-term individual based studies of harbour seal, bottlenose dolphin and fulmar populations in the North of Scotland, with comparative studies conducted at a range of overseas sites across the North Atlantic, North Pacific and South America. A key aim of the work has been to directly support regional conservation and management programmes, and through this to develop generic understanding and best practice case studies that provide insights into marine resource management issues elsewhere in the world.
