    Background

    I have obtained my formal degrees researching freshwater fishes: Honours (1996) on taxonomy of fighting fishes (Osphronemidae: Betta), Masters (1999) on faunistic survey of the fishes of Batang Hari basin in Sumatra, and PhD (2003) on Systematics of Borneo Suckers (Gastromyzontidae: Gastromyzon, Neogastromyzon and Hypergastromyzon). I have published widely with more than 100 international refereed papers and described more than 110 new fish taxa, including one of the smallest vertebrate animals – Paedocypris progenetica from peat swamp forest habitats. At present, I am involved with ecological and conservation work of freshwater fishes in Singapore, documentation of the marine fishes of Singapore, and continuing in taxonomical pursuits in freshwater and coastal fishes of Southeast Asia.

    Areas of interest

    Systematics of Southeast Asian freshwater fishes; Coastal fishes; Fish ecology

    Current projects

    - Ecology of non-native fishes in Singapore

    - Taxonomy and biogeography of Southeast Asian freshwater fishes

    - Visual records of Southeast Asian freshwater and coastal fishes
