I am interested in ecology and biodiversity conservation with a particular focus in sea turtles. My current work is looking into the impacts of increasing temperatures on sea turtle offspring. I’ve also been involved in projects carrying out beach assessments, nesting abundance surveys and satellite tracking.

Broad research interests:

  • Sea turtle ecology
  • Marine Conservation
  • Fisheries
  • Bird ecology
  • Climate change


  • 2019 PhD, University of Exeter
  • 2013 MSc Conservation and BiodiversityUniversity of Exeter
  • 2008 BSc Environmental Science, University of Plymouth


Research interests

Research projects

Project Title: Evaluating the impact of climate change on the Ascension Island green turtle, Chelonia mydas, rookery.

Supervisors: Prof. Annette BroderickProf. Brendan Godley and Dr. Sam Weber

Funding Body: NERC case partnership with Ascension Island Government

Project Description:

  • To experimentally establish sex-determining temperatures
  • To estimate current offspring sex ratios
  • To model the impacts of predicted climate change
  • To investigate natural population resilience to climate change
