Research areas
I am a marine ecologist interested in species interactions and how these relate to population dynamics. My research involves the use of biologging technologies, photo-identification, diet analysis and strandings information to investigate the foraging ecology of sympatric marine predators. My current role is investigating seal diet from regional populations around the UK.
To find out more information about our project investigating marine mammal predation by grey seals, and how you can get involved, please see our SMRUsealpred project webpage.
