Research Interests and International Engagement

My research focus is on the plant biodiversity of Southeast Asia, particularly on the families Apocynaceae and Gesneriaceae. I have undertaken revisions of several genera in Apocynaceae, subfamilies Rauvolfioideae and Apocynoideae, and completed accounts for the Flora of Thailand, Tree Flora of Sabah and Sarawak, Flora Malesiana, Flora of Peninsular Malaysia and Flora of Cambodia, Laos and Vietnam. My other main area of research interest is on the taxonomy of Southeast Asian Gesneriaceae, particularly on the genus Aeschynanthus and on the family in Thailand and Indochina. This has also involved collaboration with phylogenetic systematics to clarify generic delimitations. There are large numbers of undescribed taxa in Southeast Asian Gesneriaceae and documenting these, along with known taxa, large numbers of which have extremely restricted distributions, is important in order to provide the data for conservation. I also have an interest in the ferns of Thailand, Laos and Cambodia, particularly in providing tools for the identification of taxa. In addition I am the editor-in-chief of Gardens’ Bulletin Singapore, on the Board of the Flora Malesiana Foundation, the Editorial Board of the Flora of Thailand and the Editorial Board of the Thai Forest Bulletin (Botany).

 

Current Research

  1. Flora of Singapore.
  2. Coordination and taxonomic work on the Gesneriaceae for the Flora of Thailand.
  3. International collaboration with other Gesneriaceae systematists to clarify generic limits.
  4. Revision of Aeschynanthus.
