Freshwater ecology; Community ecology; Ecosystem functioning; Biological invasion
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 and attempted to elucidate mechanisms underlying important ecological processes.
I am currently working on modelling freshwater food webs using data from gut content and stable isotope analysis. Together with other members of the lab, we hope to use these models predictively to inform the management of freshwater habitats. I am also working on assessing the impacts of anthropogenic stressors on various measures of ecosystem functioning (e.g., food webs).
