Dr Jo Garrett is a Research Fellow at the European Centre for Environment and Human Health (ECEHH) focused on the interactions between human health, well-being, and the environment. Jo is predominantly a human geographer, utilising quantitative and GIS approaches.

Jo currently works on the 'Renewing biodiversity through a people-in-nature approach' (RENEW) project; HEROIC: Health and Economic impacts of Reducing Overheating in Cities; and the REGREEN project, focused on valuing nature-based solutions in cities. Jo also leads the EXPO-ENGAGE project which aims to co-produce a research plan for air quality citizen science in two areas in Cornwall and South Wales.

Previous projects include: RECONECT – utilising systems thinking in nature-based solution evaluation and BlueHealth – analysing survey data to explore the links between blue spaces and well-being.

Jo joined the University of Exeter in 2012 to carry out a European Social Fund PhD with the title “Interdisciplinary study into the effect of a marine renewable energy testing facility on underwater sound in Falmouth Bay”. This involved recording underwater sound over 18 months during trialling of the Fred Olsen wave energy converter, BOLT Lifesaver, at the Falmouth Bay Test Site.
