Senior Research Associate


My research focuses on predicting the effectiveness and understanding the impact of conservation policy interventions aimed at delivering behavioural change. I am particularly interested in the use of experimental economics and indirect questioning approaches in the investigation of illegal behaviour, and is using the understanding gained from such techniques to improve conservation practice.

The majority of my research focuses on conservation in Uganda and Cambodia.

I am currently working on a 3 year impact evaluation of a long running payments for ecosystem services programme called Ibis Rice in northern Cambodia. This evaluation will combine a randomised control trial and quasi-experimental methods to investigate the wellbeing and behavioural impacts of Ibis Rice. You can find out more about this project here.

In Uganda, I am currently working on a Darwin funded project Can health investments benefit conservation and sustainable development? This project focuses on evaluating the impact of primary health care interventions linked to conservation on both conservation and health outcomes around Bwindi Impenetrable National Park, a key site for the conservation of mountain gorillas.

I am also working on a follow up to our recently ended project Building Capacity for Pro-Poor Responses to Wildlife Crime in Uganda Project, which was funded by the Illegal Wildlife Trade Challenge Fund and completed in collaboration with the International Institute for Environment and Development, the Wildlife Conservation Society Uganda Programme and the Ugandan Wildlife Authority. This new project will help to implement the community based action plan for combatting wildlife crime at Murchison Falls National Park, which was developed as part of our previous project, and assess its impact on the drivers and prevalence of wildlife crime.
