    Profile

  • Sandun J. Perera, PhD, is a naturalist and a field ecologist, with a particular interest on Biogeography, Ecology, Evolutionary Biology, Biodiversity and Conservation Science. He is currently a Senior Lecturer at the Department of Natural Resources, Faculty of Applied Sciences, Sabaragamuwa University, Sri Lanka, where he graduated from the first batch of the said Department. He possesses field research experience in biodiversity, biogeography, ecology and conservation, especially in inventorying biodiversity around Sri Lanka and in South Africa, professional experience in biodiversity conservation and management at IUCN, Sri Lanka and teaching experience on biogeography, biodiversity and conservation science at the Sabaragamuwa University, Sri Lanka and the University of KwaZulu-Natal, South Africa. His doctoral research focused on the patterns of animal endemism in Maputaland-Pondolnad-Albany biodiversity hotspot, while he is currently interested in evolutionary biology and conservation biogeography of the Western Ghats and Sri Lanka biodiversity hotspot. Sandun’s scope on biodiversity research often goes beyond the level of species looking into the big picture of macroecology and biogeography, while at taxon level the interest varies from all groups of vertebrates to few selected groups of invertebrates and in terms of species from the Indian robin through sambar and slender loris to marine turtles.
