Overview

My research group focuses on marine ecology, looking specifically at the distribution and behaviour of turtles, sharks and other mobile marine species. Acquiring this knowledge is often challenging so my work uses a wide range of technologies, including satellite tracking and acoustic detection. I am especially interested in using large sets of data to assess the effects of human activities on marine ecosystems.

I am a member of the College of Life and Environmental Sciences and work across two of Exeter's campuses. At the Streatham Campus (Exeter) my research contributes to the Environmental Biology theme and on the Penryn Campus (Cornwall) my reserach contributes to the Environment and Sustainability Institute.
