Tan Koh Siang
Senior Research Fellow
Tan Koh Siang is Senior Research Fellow and Head of the Marine Biology and Ecology Laboratory at TMSI.
He obtained his PhD (Zoology) at the National University of Singapore in 1996 and was postdoctoral scholar at the Swire Institute of Marine Science, University of Hong Kong before joining TMSI in 1997.
His research interests focus on the systematics, biology and feeding ecology of tropical marine molluscs, with occasional forays into sponge taxonomy and seawall ecology.
Current research projects at SJINML revolve around deep-sea biodiversity assessment, biology of alien invasive mussels, and invertebrate interactions on seawall surfaces.
Dr Ow Yan Xiang
Dr Ow Yan Xiang is a Research Fellow with St John Island National Marine Laboratory, Singapore. After graduating from the National University of Singapore, she joined the Tropical Marine Science Institute, NUS, to work on Singapore’s coral reefs.
To gain more insight into how marine phototrophs adapt to their environment, she did her PhD with James Cook University, Australia (2012-2015) to study the physiological responses of tropical seagrasses to declining water quality and ocean acidification at the Great Barrier Reef, Australia.
Before joining SJINML, she held a post-doctoral research fellow position with the Department of Biological Sciences, NUS. Her research interest lies in examining the mechanisms through which marine phototrophs (i.e. corals, seagrasses, algae) respond and adapt to changes to their environments.
Dr. Neo Mei Lin
Dr. Neo Mei Lin is a familiar face at the St John’s Island National Marine Laboratory, having started her research work on the giant clams since 2006.
Her current research expertise lies in the mariculture of giant clams, experimental marine ecology, and marine conservation.
Mei Lin is also an advocate for science communication and to bring a voice for the conservation of giant clams. Outside of research, she actively volunteers in local conservation groups to promote marine conservation messages and educate fellow volunteers.
