PhD Students

I supervise PhD students across several different departments (Geography, Computer Science, Politics, Psychology) and two universities (Exeter, Bath) – a reflection both of the interlinked and interdisciplinary work we do on climate change communication and of the UK PhD funding landscape. All students based in the Geography department at Exeter University are part of the large, active and friendly Environment & Sustainability Research Group.

Working with PhD students really is one of the best parts of my job. I’ve been proud to see my students publish their first (and subsequent!) papers, submit their PhD theses, engage with policy and practitioner debates, and continue into diverse and rewarding careers in the social science dimensions of sustainability. The following is a list of my PhD students, who I consider myself fortunate to (have) work(ed) with:

I work with the following PhD researchers as lead supervisor:
