Taxonomic and floristic research in South East Asia, especially Primulaceae and Stemonuraceae; field guides to Thailand, Borneo and New Guinea; floristics and conservation of New Guinea; organiser of the Tropical ID Course.
Systematic research on the families Primulaceae, especially the genus Maesa, and the Icacinaceae, and Stemonuraceae. Maesa is a taxonomically complex genus with its centre in South East Asia, and work includes researching species variation in the region and will result in the production of floristic treatments. The Icacinaceae were poorly known and work has been undertaken on generic limits, as well as undertaking floristic research in the newly segregated family Stemonuraceae.
Also researching several other families from South East Asia, especially from New Guinea, describing new species etc., including the Annonaceae, Hamamelidaceae, Rubiaceae, Pittosporaceae, and Scrophulariaceae.
Member of the Mt Jaya project, exploring New Guinea’s highest peak, and involved in fieldwork in the region, writing taxonomic accounts, and editing the book and seeing it through to publication. Research into collecting patterns on Mt Jaya and the island of New Guinea as a whole, and their effects on planning botanical inventories and databasing, and setting conservation priorities in New Guinea.
The South East Asia team has successfully participated in several Darwin Initiative grants. Including, Papuan Plant Diversity, Field Guide to the Forest Trees of Southern Thailand, an inventory of conservation areas of Sabah, and monitoring a lowland forest restoration project in Sumatra.
Approach is that of a generalist botanist with a broad knowledge of the flora of South-East Asia and Indochina, with special interest in New Guinea, undertaking identification of incoming herbarium material. The South East Asia team organises and runs an annual Tropical Plant Identification Course, which has been very well received since its launch in 2003; and is currently preparing a handbook based on the course content.
