Freshwater and Invasion Biology Lab

PhD NUS, BSc (Hons) NUS

Teaching Areas:


BL5230 – Invasion Biology
LSM3254 – Ecology of Aquatic Environments
LSM4263 – Field Studies in Biodiversity
LSM4264 – Freshwater Biology
LSM4266 – Topics in Aquatic Biodiversity


Research Areas:

Freshwater ecology and biodiversity
Aquatic invasions
Freshwater decapod crustaceans (systematics, biogeography, and conservation)


Current projects:

Projects (together with students, staff, and collaborators) include biodiversity surveys and ecological studies of Singapore’s freshwater fauna such as plankton, invertebrates, and fishes; ecological studies of aquatic alien species in Singapore and tropical Asia; and systematics and taxonomy, biogeography, and conservation of freshwater crabs and other freshwater decapod crustaceans.

  1. Freshwater ecology and biodiversity – Ongoing ecological work focuses on Singapore’s reservoirs including investigations of toxin production by cyanobacteria and their responses to environmental variables; food web and trophic interactions; and origins and ecology of freshwater molluscs.

  2. Aquatic invasions in tropical Asia – Investigating invasiveness, ecology, and impacts of aquatic alien species, e.g., investigating competitive interactions between introduced gobies (marbled goby, Oxyeleotris marmorata and bar-cheeked goby, Rhinogobius giurinus) and native species; and impacts of piscivorous alien fish species on sexual selection in native species of halfbeaks (Hemirhamphidae). Other introduced species studied include the redclaw crayfish (Cherax quadricarinatus), golden apple snail (Pomacea canaliculata), threadfin acara (Acarichthys heckelii), guppy (Poecilia reticulata), and American Bullfrog (Lithobates catesbeianus).

  3. Freshwater crabs – Work includes phylogeographic and taxonomic studies of Asian freshwater crabs; global IUCN Red List conservation assessments; and ecological and conservation studies of critically endangered species, e.g., the Singapore freshwater crab (Johora singaporensis).
