I am primarily a Weed Scientist and a former Associate Professor (on Merit) of Botany, University of Colombo, Sri Lanka. Presently, I am the Director of Nature Consulting Australia. I am also the founding Editor-in-Chief of WEEDS, the Journal of the Asian-Pacific weed Science Society (APWSS). As a secular humanist, I want to: 'be the change that I wish the world to be' (Gandhi quote).
