About my experience and expertise

Personal statement:

I’m a environmental psychologist with expertise in the application of psychological theory and methods to biodiversity conservation questions. Collaborating with ecologists, I use quantitative methods to assess mental health & wellbeing impact of biodiversity, and use qualitative methods to apply behaviour change theory to conservation problems.

I was a collaborating author of the IPBES Values Assessment, co-author of a WHO report on blue and greenspace and mental health, and sit on the British Psychological Society’s Climate Environment Action Coordinating Group. I am an Associate Editor the British Ecological Society journal People and Nature.

Key topic areas of research or interest:

My research interests focuses primarily on two key topic areas:

(1) Biodiversity & behaviour change: Applying behaviour change theory to address biodiversity conservation problems. In particular, I audit national biodiversity policies to identify gaps and understand how to improve policies

(2) Biodiversity and mental wellbeing: Working with ecologists to understand the impact on mental health and well-being of contact with biodiversity (and different habitat types), and the mediating pathways of this relationship.

Collaboration opportunities:

I’m always open to collaborations, PhD projects, consultancy, media work and all other forms of engagement that link to my areas of research. Enjoy brainstorming with ecologists!
