I am a graduate from University of Colombo with a Second Class (Upper Division) Honours in the area of Mathematical Finance. After graduation I joined the Department of Mathematics, University of Colombo as a Temporary Instructor in 2010. In 2011, I joined the Department of Management Sciences, Uwa Wellassa University as a Temporary Demonstrator. I also have worked in the Department of Mathematics, University of Colombo as a Temporary Assistant Lecturer in 2012. Later 2012, I joined as a PhD Research Assistant at the Department of Mathematics, University of Colombo. At present I am working at the Department of Mathematics & Philosophy of Engineering, Faculty of Engineering Technology, The Open University of Sri Lanka, Nawala, as a Lecturer (Probationary).
