Role: 

Management of the Kew Madagascar Conservation Centre (KMCC) and coordinator of Kew’s programme in Madagascar.

Expertise: Phyllanthaceae, Euphorbiaceae, environmental education, plant diversity and conservation in Madagascar.

Management of the Kew Madagascar Conservation Centre (KMCC), including coordination of its research and conservation programme. My systematics research focuses on the Euphorbiaceae and Phyllanthaceae, including a revision of Madagascan Phyllanthus and their conservation assessment. Over 90% of Madagascan plant species are endemic and many have highly restricted distribution. My work on our overall knowledge of patterns of diversity in Madagascar is helping to inform conservation planning, particularly the prioritization of species and areas. The education programme focuses on three key areas:

1) informing communities about local biodiversity, conservation, appropriate livelihoods and development practices e.g. energy efficient stoves

2) informing schools about biodiversity and conservation in Madagascar and providing materials for teachers

3) professional training for Malagasy researchers and Kew MSc. students.
