I am a research scientist, a university teacher and a birder. My research interests are rooted in the studies of island biogeography, causes of endemicity and the evolution of novel traits. My approach uses both field- and laboratory-based research grounded in a strong conceptual framework to address processes underlying trait divergence and species (trait) boundaries - mainly in birds. Sri Lanka, where most of my field sites are located, in particular offers a great assortment of species assemblages to study critical questions related to speciation in island biogeographic framework.
