Interests include ecology of tropical rivers, lakes, peat swamps and mangrove forests. Present research focuses on the ecology of tropical peat swamp forests, an extreme and endangered environment (low pH, low nutrients, low oxygen). Leaf litter decomposition and peat formation, particularly with respect to microbial ecology and nutrient cycling is being studied. New species of algae, fungi and invertebrates have been discovered, including forms never before observed.
Another topic of interest is a comparison of ecosystem functioning of tropical headwater streams in different forest types and at different altitudes, focussing on leaf litterbreakdown by invertebrate shredders of Malaysian streams along an altitudinal gradient and microbes. These studies are contributing to a worldwide comparison of tropical- temperate stream ecosystem function.

Current Research Projects:
Recent studies have focused on invertebrate shredders in Malaysian streams as part of a collaborative worldwide study entitled ‘Biodiversity effects on ecosystem function. A test with a consumer guild across latitudes’ funded by the National Geographic Society.
Another study is on carbon cycling in a tropical Malaysian peat swamp. Nutrient dynamics are being investigated with results suggesting that bacteria support a large proportion of aquatic biomass. Terrestrial and aquatic litter and fruit decomposition has been found to be extremely slow, despite the presence of fungi and bacteria.
Prospective Research Projects:
I am happy to supervise projects related to the ecology of tropical peatswamps, streams and lakes, particularly studies related to trophic interactions, nutrient cycling and leaf litter decomposition. I am willing to discuss any potential projects that are related to tropical aquatic ecology.
