Undergraduate Research:
Unfortunately,
I will not be able to supervise any UROPS or honours students
in the coming academic year (2008/2009) as I am currently
overseas on study leave (until Aug 2009)
Research Area:
Systematics and taxonomy of crabs (Crustacea: Decapoda: Brachyura)
Research Interests:
Most of my current research focuses on the taxonomy and systematics of various groups of Asian freshwater crabs (Superfamilies Potamoidea and Gecarcinucoidea). These crabs are regarded as 'true freshwater crabs' because of their life cycle being independent of the sea, i.e. lacking a marine larval phase. Freshwater crabs are highly speciose and are prominent members of their respective ecosystems, but remain poorly studied in many parts of Asia; their species diversity is probably greatly underestimated. Freshwater crabs also serve as excellent indicators for biogeographical studies. Against a background of rapid development and habitat destruction, there is an urgent need for continued exploration and taxonomic and diversity studies on freshwater crabs. In addition to taxonomic studies, I am carrying out collaborative phylogenetic and biogeographical studies with international colleagues on various groups of freshwater crabs using molecular and morphological methods. I am also conducting taxonomic research on selected groups of marine crabs and am involved in a collaborative research project with colleagues at the Raffles Museum of Biodiversity Research (RMBR) to study the diversity of the marine Brachyura of Singapore as well as selected groups from the South China Sea.
Additional research interests:
I have also previously worked on freshwater prawns (Decapoda: Caridea) from the families Palaemonidae (genus Macrobrachium) and Alpheidae (genus Alpheus and Potamalpheops), and continue to maintain an interest in these groups. I am also currently involved in preliminary collaborative investigations of exotic freshwater crayfish (Crustacea: Decapoda: Parastacidae) occurring in Singapore. This may later be expanded into a comprehensive study of this group of animals in Singapore.
Current projects:
- Systematics, biogeography and taxonomy of freshwater macro-arthropods (including freshwater crabs) of Indochina.
- Systematics and taxonomy of the freshwater crabs of Sri Lanka and India.
- Morphological and molecular phylogeny and biogeography of selected groups of Asian freshwater crabs (including endemic freshwater crabs of the Wuyi mountain range, China , with associated studies on lung fluke Paragonimus).
- Systematics and taxonomy of freshwater crabs of Pakistan.
- Diversity of freshwater decapod crustacean fauna of Anambas and Natuna Islands, Indonesia.
- Marine brachyuran diversity of Singapore.
- Diversity and taxonomy of selected groups of marine Brachyura in the South China Sea.
- Preliminary investigations of freshwater crayfish in Singapore.
