I graduated from University of Colombo in 1986 and did my M.Sc. and M.Phil both in the area of Analytical Chemistry at the University of Colombo. I am interested in applicable research such as water purification and hydroponics. I was able to do a social project on hydroponics and won Technology Award for excellence from NFS.
