Conservation and systematics of South East Asian plants; Verbenaceae and Lamiaceae in particular.
The generic definitions within the South East Asian Verbenaceae/Labiatae are confusing at the moment. The genera are taxonomically complex and many problematic species occur within the region. Redefining generic boundaries and producing floristic treatments for the region is the main focus of current taxonomic research.
The South East Asia team are involved with projects (many funded by Darwin initiative grants) requiring a broad knowledge of the flora of South East Asia and Indochina. Examples include the current projects to produce a Field Guide to the Forest Trees of Southern Thailand and a handbook for the identification of commonly encountered tropical plant families. A recent joint Leiden/Kew initiative produced an interactive key to Malaysian Seed plants which has since been published online.
Additional responsibilities involve leading the SE Asian Team and managing the curation and research within the regional teams.
