I am doing my PhD based on my MSc. project which I carried out at the University of Indonesia in 2005. There are still many scientific questions to answer.  My research is about the rattan, which is a famous taxa within Palms family, and Indonesia is one of the biggest rattan producer countries in the world.

Research interest

Calamus javensis is one of the very polymorphic rattan species (climbing palms) spread over SE Asia and W Malesia. The species concept is a problem, in the course of time several species have been recognised and united again, likewise with many infraspecific names.

The cane of Calamus javensis is among the major commercial rattans, second in quality to Calamus caesius. Rattan forms one of the minor forest products in Asia, but the collection of it provides a major source of income to many locals. Future research should clarify which forms in the Calamus javensis complex provide the highest quality rattan. In the present study the distribution areas of the local forms can already be modelled via Species Distribution Modelling (via the ecological traits of known collection localities, all other localities can be evaluated for suitability, resulting in a distribution model for the forms). These models, linked to species abundance and soil use can indicate which forms are threatened with extinction and which forms can still be collected for their rattan in an as much sustainable way as possible.

Purpose of the PhD research is to clarify the species concept by sequencing DNA for phylogenetic and phylogeographic analyses. This can best be done on silica dried material collected in the field. The species complex is most diverse in N and W Borneo (Sabah, Brunei, Sarawak).
