Role: 

My research programme is concerned with the diversity of desert plants in a changing world.

I study global patterns in succulent plant diversity and the evolutionary processes underlying their extraordinary adaptations and ecological success. Much of my work is focussed on African succulent plants, particularly the charismatic genus Aloe (Xanthorrhoeaceae). I’m interested in phylogenetics as a tool for identifying patterns in plant value and useful properties, and how these can be applied to decision-making around priority species in research and conservation.

My research approach integrates the laboratory with field observations, and curated living collections of plants in botanic gardens. At Kew, I contribute to various projects to enhance science in the garden, including the restored Temperate House which re-opens in 2018.
