Research into the systematics and conservation of useful plants in Africa

My research interest is in the classification and conservation of useful plants in Africa, combining systematics with ethnobotany and conservation biology. Recent studies have focussed on Aloe (Xanthorrhoeaceae), a group of great economic and cultural importance and taxonomic complexity. Improved understanding of both classification and use patterns in Aloe will help to address the utility potential of some species and conservation concerns for others.

I also assist the Head of the Sustainable Uses Group in delivering the research objectives of the team with a geographic focus on Africa, engaging with our varied collaborators to gather data and disseminate information. I contribute to teaching the Kew-University of Kent MSc in Ethnobotany.
