Wijeyaratne It is my privilege and pleasure to pen this message of felicitation for the flagship event in our annual calendar – the Annual Research Symposium. Teaching, research and scholarship are the fundamental constituents that reveal the quality and relevance of any seat of higher learning. The Annual Research Symposium of our university provides an ideal opportunity to highlight the research capability and potential of our own academic staff and students. This year’s symposium portrays these attributes with a greater magnitude in scope and outlook, by being conducted as the culmination of the two key events of the Asian Universities Alliance (AUA). The University of Colombo is the only Sri Lankan university among the fifteen-member consortium that comprises this esteemed alliance. Our university has the added privilege of holding the Executive Presidency in 2019, which brings with it the responsibility of hosting the Executives’ Meeting and the Youth Forum of the Alliance. Our symposium this year is centred around the chosen theme “Health and Well-Being” that serendipitously provides the perfect platform to celebrate the 150th anniversary of the birth of this institution in the form of the Ceylon Medical College. Therefore, the symposium and the AUA events that are occurring simultaneously give us an opportunity to truly celebrate our university and its potential. Almost all the events are scheduled to take place within the university precincts, with College House – a symbol of our cultural heritage – as the focal point. Our events are strengthened by the support and collaboration of the Ministry of Higher Education and the World Health Organisation. This indeed has raised the bar of our academic profile with a clear validation of the relevance of our outputs from a national context. We are honoured by the presence and participation of the Presidents and key decision makers of the best universities in Asia, who are our partners in the AUA. 1 Their contributions have added value to our programmes. It is my fervent wish that the initiatives taken at these fora will not be confined to fostering closer ties between our institutions, but will also lead to effective networking and more productive collaborations that would benefit the wider society in which we live and serve. I also take this opportunity to felicitate the organizing team of academics, researchers, administrators and students, so ably led by Chairperson Prof Naazima Kamardeen and by the administrative lead for research and development Ms Tharushika Pathiranage, and the multitude of administrators and support staff alike. I thank our sponsors and well-wishers, chief among them our alumni. My very best wishes for fruitful deliberations go out to all of you. 2 MESSAGE FROM THE SYMPOSIUM CHAIR ANNUAL RESEARCH SYMPOSIUM 2019 Professor Naazima Kamardeen It is with great pleasure that I pen these words on the occasion of the Annual Research Symposium of the University of Colombo for 2019. This annual event showcasing the research capabilities of our staff has taken a new dimension this year, as it coincides with the Executives Meeting and Youth Forum of the Asian Universities Alliance, which our University is proud to host. In keeping with the timely theme “Health and Well-Being” which connects meaningfully with the 150th anniversary of our university’s oldest institution, the Faculty of Medicine, our annual research symposium this year promises a stimulating array of events that highlight the role of the University of Colombo as the premier research institution in Sri
