Current research topics

Currently I am part of The Malesian Key Group and working on the on-line Interactive Key to Seed Plants of Malesia and Indo-China. The part I work on is on the Leguminosae. 

The Interactive Key to Malesian Seed Plants is an identification system for all native and naturalised (i.e. introduced species with self-maintaining 'wild' populations) families of the Flora Malesiana region (including Malaysia, Brunei, Singapore, Indonesia, Philippines, East Timor and Papua New Guinea) and Indo-China. The key is based on a set of characters  chosen because they are relatively easy to assess from any reasonably intact flowering and/or fruiting specimen. The key is mainly based on the books by Max van Balgooy (MALESIAN SEED PLANTS - Spot Characters (1997) and Plant Portraits (1998, 2001)) and incorporates additional information from L. Watson and M. J. Dallwitz "The Families of Flowering Plants: Descriptions, Illustrations, Identification, and Information Retrieval. All data are checked by us with herbarium material.


I work on the Key project together with researchers in Kew (Rogier de Kok, Don Kirkup, Tim Uttridge)

With Frits Adema I work together on the Leguminosae for the Flora Malesiana



Available student projects

Public outreach

The interactive Key to Seed plants of Malesia and Indo-China (http://www.kew.org/herbarium/keys/fm/index.html) can be used for teaching students.
