My research interests focus on how marine mammals’ utilise the dynamic nature of their environment and how they adjust their behaviour in response to changes in their environments.  This includes natural environmental changes and responses to man-made perturbations.  As we see the increasing urbanisation of marine environments, I am particularly interested in how marine mammals perceive and respond to novel man-made sources in the ocean.

Current projects

Impacts of marine renewable energy technologies

Many countries have set ambitious targets for renewable energy, with energy from offshore sources anticipated to form an important part of this; this has led to the proposed installation of wind, wave, and tidal energy converters around the coast. However, these potentially hazardous to marine mammals and understanding how they perceive and respond to renewable devices is critical to ensure that they can co-exist at the scales currently being envisaged for the industry. My research includes studies of the impacts of wind farm construction on harbour seals and behavioural responses of seals to tidal stream energy devices.

Effects of underwater noise on foraging efficiency

There is increasing evidence that man-made noise can compromise decision-making during foraging which may lead to reductions in foraging efficiency and ultimately individual fitness of a range of species. I am interested in understanding how the foraging efficiency of air breathing marine predators, which have relatively rigid physiological constraints, can be affected by underwater noise.

Use of dynamic habitats by marine predators

In marine systems, tidal and meteorological processes, together with geographical features such as narrow coastal channels effectively create habitats that are in constant flux due to water movements. My research looks to understand the unique challenges and opportunities this creates for marine predators using them.
