About Me

I have obtained a First class BSc honours degree in Geology from the University of Peradeniya, and the MSc degree in Engineering Geology from the Asian Institute of Technology (AIT), Bangkok, Thailand. I received my PhD degree from the Saga University, in Japan in Geotechnical Engineering. I joined the University of Peradeniya, Sri Lanka in 1993 as a Lecturer (probationary) and promoted as a senior Lecturer in 2001 attached to the Department of Geology, University of Peradeniya. I served as the Head of the Department for 3 years (2013-2016) and have served as the chairman of the Board of Study in Earth Sciences of the Postgraduate Institute of Science (PGIS). I am the Coordinator of the MSc programme in GIS & Remote Sensing as well as MSc programme in Engineering Geology & Hydrogeology attached to the PGIS. I have supervised over 250 Postgraduate MSc thesis, 5 MPhil thesis, 1 MD thesis and 3 PhD thesis during the last 20 years. I have served in several University Committees and presently serving as the director of the Sri Lanka Japan Study Centre (SLJSC)  and the Deputy Director of the Centre for Environmental Studies (CES).
