I am a B Sc hounors graduate (in Botany) from University of Peradeniya, Sri Lanka (1980) and I have earned an M Phil degree from the same university in 1990 for the thesis based on research that I carried out on structural and functional properties of mangrove ecosystems of a lagoon on the north western coast of Sri Lanka. I pursued Ph D studies in Environmental Science at the University of Salford, UK and I was conferred the degree for the thesis submitted on “Environmental assessment for wetland management in Sri Lanka” which involved development of EIA methods particularly for tropical wetlands. I served as a scientist at the National Aquatic Resources Agency of Sri Lanka for 15 years and was engaged in research on coastal wetland ecology and management in Sri Lanka. I also participated in collaborative research with other local and overseas institutions including universities, research institutions and community-based organizations. Subsequently I joined the Department of Botany at the Open University of Sri Lanka in 1997 as a senior lecturer and was involved with development of post-graduate programmes in Environmental Science and production of audio-visual material for teaching Ecology. I joined the Department of Botany in University of Kelaniya as a senior lecturer in 1998. In 2000/2001, I taught Tropical Wetland Ecology and Management in a postgraduate programme on “ Environmental Management in the Third World” conducted by the Royal Holloway College, University of London. In addition to undergraduate teaching I also was involved with developing a postgraduate programme on Biodiversity and Integrated Environmental Management at the Department of Botany and at present serve as its coordinator.
