I graduated from the University of Peradeniya, Sri Lanka, following a B. Sc. (Special Degree in Botany) in 1993. After my graduation, I served at the Department of Botany, University of Peradeniya as an Assistant Lecturer until I joined the Open University of Sri Lanka as a Lecturer (Probationary) in 1993. I received a scholarship from the Commonwealth scholarship Commission in the UK for my PhD  and  obtained my PhD from the University of Aberdeen, UK , specializing in the field of Plant Molecular Enzymology in 2001 (Oct. 1997 – Feb. 2001). Further I received a Commonwealth Academic Fellowship  and successfully completed  my Post Doctoral study at the same university in 2008 ( Sept. 2008 – Feb. 2009).

Currently I am serving as a Senior Lecturer in Botany (2001 – to-date) at the Kandy Regional Centre, The Open University of Sri Lanka, Polgolla.
