Ericaceae systematics and evolution
Our research on the flowering plant family Ericaceae is centred on the genus Erica and the collections of the University gardens, particularly Rhododendron.

Main content
Research themes include phylogeny and classification; biogeography and drivers of species diversification; phylogenomics and species delimitation; pollination ecology and speciation; taxonomy
Our ongoing work contributes to the Botanic Gardens Conservation International (BGCI) Global Conservation Consortium for Erica, which is coordinated at the University Gardens.
