Background
My interest in ecology started with my undergraduate work on the autecology of an introduced fish, Acarichthys heckelii in Singapore. In my PhD work, I focused on characterising the trophic ecology of reservoir communities by modelling freshwater food webs using gut-content and stable isotope data. I also assessed ecological mechanisms underlying The structural regulation of these webs.
Projects
I am currently working on quantifying the impacts of anthropogenic land-use change on freshwater food webs. Specifically, I will characterise temporal changes in maximum food chain length and relative allochthony. This will involve the use of compound specific isotope analysis and is part of a larger project aimed at eludicating the effects of anthropogenic stressors on freshwater ecosystem functioning.
