Dr. LOW Bi Wei

Bi Wei is an invasion biologist and freshwater ichthyologist by training. His PhD research at NUS focused on elucidating the ecology, genomics and impacts of the highly invasive African sharptooth catfish (Clarias gariepinus) in Southeast Asia. His subsequent postdoctoral work focused on the use of odonates as biological control of urban aquatic insect pests and the documentation of Singapore’s historical biodiversity (at NUS, 2019–2021), and the impacts (and potential mitigation) of riverine fragmentation on gene flow in Southern Chinese fishes (at Lingnan University, 2021–2023). Bi Wei is a member of the IUCN Sundaic Freshwater Fish Red List Working Group, having assessed global extinction risks for 100 species. He is also the freshwater fishes team leader for the 3rd Singapore Red Data Book.

Bi Wei’s current work focuses on developing a typology for integrating “green” and “grey” elements for coastal protection in Singapore, as well as using spatial models to identify potential sites for hybrid solutions.
