Overview
I am a marine ecologist and my research focuses on several aspects of marine turtle ecology, including both in-water research and work conducted on nesting beaches. My current research involves studying the ecology of leatherback sea turtles in Brazil, through the use of diverse techniques such as PIT tagging, stable isotopes, temperature and sex ratios and population dynamics.
Broad research specialisms:
- Marine turtles
- Marine conservation
- Population dynamics
- Spatial ecology
- Mark and recapture studies

Project Title: Ecology and conservation of the leatherback sea turtle (Dermochelys coriacea) population in Brazil.
Supervisors: Professor Brendan Godley and Dr Annette Broderick
Funding Bodies: US Fish and Wildlife Service and British Chelonia Group, in collaboration with Projeto TAMAR (The Brazilian Sea Turtle Conservation Programme) in Brazil
Project Description:
The leatherback sea turtle population in Brazil is considered critically endangered, mainly due to their restricted distribution and small population size, which makes them highly vulnerable to threats such as incidental capture in fisheries, habitat destruction/alteration and climate change. The broad objective of this project is to utilise a range of techniques, including PIT tagging, stable isotopes, the thermal profile of nesting beaches and nest counts to obtain a more complete knowledge of the spatial ecology, habitat use, population trends and threats to the leatherback turtles nesting in Brazil, hopefully contributing to achieve their effective conservation.
