My Research

I am with the Department of Biological Sciences at the National University of Singapore (NUS), where I obtained both my Honours degree with a project compiling the total vascular plant flora of Singapore, and my PhD with a thesis on the effects of greenery on urban biodiversity. I am currently on an NUS Overseas Postdoctoral Fellowship and will be based at the Centre of Excellence for Environmental Decisions, Centre for Biodiversity and Conservation Science, University of Queensland.

My research interests are in vegetation ecology, invasion ecology, and urban ecology. Currently, I am working on optimal planning of urban greenery and green spaces to maximise their value for both biodiversity and humans. My previous postdoctoral stint was on an interdisciplinary project to model vegetation-hydrology relationships in a catchment containing Singapore’s last substantial tract of intact freshwater swamp forest: the Nee Soon swamp forest. In 2011, together with Alex Yee and later funded by the Ah Meng Memorial Conservation Fund, we set up long-term plots to monitor the recovery trajectory of secondary forests after an unusually powerful windstorm resulted in extensive tree falls in the Mandai Road area of the Central Catchment Nature Reserves of Singapore. I also contribute to a number of biodversity surveys that have informed urban biodiversity protection and enhancement in Singapore, such as of the former Keratapi Tanah Melayu railway line, Coney Island, and the Ulu Pandan, Tampines, Serangoon, and Punggol waterways, etc.

I enjoy looking at data and designing studies. I am most proud of the work that I have accomplished in partnership with the students that I mentor/supervise; much of my time and effort goes into making them worthy of making it through scientific peer-review (see my track record).

I am also keen on contributing to the development of the standard of scientific research in Southeast Asia, a diverse and unique region where an understanding of local cultural sensitivities and socio-political realities is key for applied research to make a real impact.
