Background
My undergraduate project examined the influence of macroinvertebrates on leaf litter decomposition in forest streams which spurred my interest in freshwater ecology. Soon after graduation, I worked as a Research Assistant in the Tropical Marine Science Institute studying on chironomid ecology and taxonomy, followed by working as a part-time PhD student and Research Assistant. Some of the several projects in which I was previously involved include the examination of the potential environmental impacts of floating solar panels on water quality in the reservoir as well as aquatic and avian fauna using a Before-After-Control-Impact (BACI) study design. I was a postdoctoral research Fellow in NUS, where I was involved in a project to characterize food webs in Singapore’s reservoirs using stable isotopes and elucidating the mechanisms regulating trophic cascades to assess the effects of biomanipulation on the food web dynamics.
