Education and Certifications

B.S. in Zoology - University of Kelaniya, Sri Lanka

Thesis: The Zoonotic importance of domestic rat (Rattus rattus) and pet animals in some selected sites in the western province of Sri Lanka.

M.S. in Biology ( Ecology and Wildlife Management) - University of Central Oklahoma

Thesis: Integrating Camera Trap Data and Occupancy Modeling to Estimate Seasonal Variations in Occurrence, Detection, and Activity Patterns of Mesocarnivores in Southcentral Oklahoma


I consider myself as a wildlife ecologist with overlapping interests in conservation, spatial ecology, predator-prey interactions, and parasitology. I have a broad research background focused on spatial ecology, wildlife conservation, parasitology, and endocrinology.
