Research Interests

  • Molecular Systematic studies of the subfamily Gonystyloideae and Aquilaroideae of Sarawak. Funded by FRGS. 
  • Flora of Peninsular Malaysia – Project Program under FRIM, Funded by Government of Malaysia, – Review on Family Thymelaeaceae of Peninsula Malaya. 
  • Plant Diversity in different ecosystems at Sg. Asap Belaga. Funded by Malaysian Palm Oil Board.  

Plant systematic, taxonomy, ethnobotany and conservation are areas of my interest. Data on taxonomic and systematic information of certain plant families in Sarawak are still lacking. These informations are crucial especially to the economic, endemic, threatened and endangered plant species of Sarawak or Borneo as a whole. Borneo is well known as one of the world biodiversity hot spots as it has a very high species endemism and diversity. The information obtained is useful for conservation activities and sustainable utilization of the important plant species in the future.

Besides supervising undergraduate and postgraduate students on taxonomic studies on selected taxa, ethnobotany, ecology and anatomy, my current research activities includes the taxonomic and systematic studies for the genus Gonystylus, Aetoxylon, Aquilaria (Thymelaeceae); Eusideroxylon zwageri, Potoxylon (Lauraceae) funded by Intensified Research Priorty Areas (IRPA). I am also constantly contributing to the Plant Resources of South-East Asia project.
