PhD Research

I am a third year PhD student, supervised by Casey Ryan and part of the LANDteam. My PhD research broadly looks at the biodiversity and the socioeconomic links to agroforestry in the tropics.

I am developing methods for mapping biodiversity in mosaic agroforestry landscapes, working with the World Agroforestry Centre (ICRAF), contributing to a Trees on Farms’ Biodiversity Assessment Tool as part of a bigger project to improve the ability of countries to meet biodiversity targets by harnessing the potential of trees in agricultral land. I will also be exploring the links between agroforestry adoption and community socioeconomic characteristics at a national scale. For this I am developing some small area-level models of these socioeconomic characteristics using small area estimation methods.

I am currently on-pause from PhD work, developing a global indicator for monitoring the biodiversity of trees on farms, to feed into the post-2020 global biodiversity targets, which are currently being negotiated.


My PhD is mainly funded by NERC E3 Docotoral Training Partnership, with contributions from ICRAF
