My primary research interests lie in understanding the processes that form and maintain biodiversity. I am particularly interested in the study of highly diverse ecosystems and how they are molded through processes like speciation and adaptive radiation. I use spiders as models to address these issues in my research. My research to date combines these cross-disciplinary interests. Its unifying theme concerns the formulation of evolutionary conclusions using morphology, genes and behavioral studies.Specialties: Taxonomy and behavior of arachnids, Molecular and morphological phylogenetics, Systematic theory, Conservation of insects and arachnids, Environmental impact assessment, Nano biology, Orchids of Sri Lanka.
