Faculty session of the Annual research symposium 2013 will be held on 4th of October 2013, at the Department of Physics.There will be two separate sessions for Physical Science and Biological Science streams.

prof. Ariyarathne-dean-2013

The Faculty of Science of the University of Colombo is dedicated to providing an environment for our academic staff and postgraduate students to conduct high quality research. We place a heavy emphasis on research and, as a result, our faculty is at the forefront in generating invaluable scientific knowledge and information which has been disseminated at important national and international forums. The Annual Research Symposium hosted by the university will provide a strong incentive particularly for young academics who are making a head start as researchers. The scientific papers and the thought provoking discussions that follow would no doubt promote and enhance the research culture in the Faculty of Science.

The selected theme for this year, “Higher Education through the State Sector of Sri Lanka in a Competitive Knowledge Economy”, would indeed be of special relevance to us at the Faculty of Science, as we strive to attain international standards in the competitive field of research and development. I am therefore thankful to all those who submitted abstracts and to those who were involved in reviewing and editing them. I am sure these sessions will be of immense benefit to both contributors and participants and would provide an ideal forum to formulate collaborative research in the field of science.
I wish the Annual Research Symposium 2013 every success.
