President's Message

Message by the President

I am honored to be inducted as the President of the Physiological Society of Sri Lanka for the year 2026. In the coming year, I hope to continue the legacy and vision of the brilliant academics and great role models who established this umbrella body 39 years ago, unifying all physiologists in the country, to search, teach, serve, and network. I thank the previous council, led by Professor Dinithi Fernando, for the successes and wisdom (and some challenges) they passed down to me and the present council.

As we have been conducting over the years, the 2026 PSSL calendar comprises two main activities for academics: the Regional Meeting, and the Annual Scientific Sessions. The Regional Meeting (March 2026), will be an academic and social event, that knits geography and generations, as the founders of the PSSL envisioned. The Annual Scientific Sessions with its prestigious orations, symposia and free paper sessions, will be of scientific merit on par with the world. I warmly invite all physiologists, allied scientists and clinicians to submit their research to the PSSL Annual Academic Sessions held in November 2026. This will also be a great opportunity to network with your colleagues in a fostering ambience.

In an era with unprecedented advancement and democratization of knowledge, teachers or textbooks can no longer claim their unquestionable authority on a subject. Physiology is no exception. Students are more in need of role models, and guidance on how to learn and build their career without being supercompetitive. To this end, this year’s council plans to conduct a networking activity with a soft competitive element (instead of a traditional physiology quiz) for physiology undergraduates, to promote their career development, scientific thinking, and efficient and responsible use of technology in their research and learning. The expertise and mentorship of senior physiologists of the PSSL are pertinent in this endeavor.

Running a national-level scientific society with international collaborations in a time of brain drain and financial hardships is challenging. The spirit and support of the membership, potential granting bodies and benefactors will be of immense strength for the PSSL to navigate these testing times.

Over the last 39 years, the PSSL has become increasingly vibrant. Today, the membership consists of basic physiologists, applied physiologists and clinicians, who collaborate seamlessly in providing state-of-the-art teaching and service functions, and conducting translational research. I believe that this is a rare gift for an academic body: The future of the PSSL lies in this diversification of its membership and unification of its goals, so that we are able to cater to the changing landscape of academia, science, and human wellbeing. Hence this year’s theme: ‘Strengthening the Synapses of Physiology: from Cells to Systems to Society’.

I thank all colleagues who joined this year’s PSSL executive committee, and look forward to an exciting year ahead.

The Physiological Society of Sri Lanka

Welcome and thank you for visiting the website of PSSL - The Physiological Society of Sri Lanka.

The Physiological Society of Sri LankaThe Physiological Society of Sri Lanka is the only society in Sri Lanka which promotes fellowship among the physiologists to improve teaching of Physiology, encourages and supports research in Physiology, helps disseminate knowledge in various aspects of Physiology and promotes involvement of Physiologists in community development.

Importance of Physiology

The PSSL is proud of its track record of having organised the Koch and K.N. (Bull) Seneviratne Memorial Orations on several previous occasions, including the worst of times in our recent history. The PSSL itself is poor, but we are content because we have been rich and rich enough in the intellectual quality of the orations we have offered annually.

Though the role of the discipline of Physiology in the medical curriculum is no longer a major one, the importance of human Physiology, the scientific study of how the body works, remains undiminished. We believe that it is the proper study of humankind.

A Tribute to Prof. Carlo Fonseka From the PSSL

A Message from Prof. Vajira Weerasinghe

Prof. carlo fonseka

Prof. Carlo Fonseka is a legend in Physiology in Sri Lanka. From the time of obtaining a PhD in Physiology from the University of Edinburgh in UK in 1966, his contribution to the field of Physiology has been colossal. He is considered as one the best lecturers in Physiology because of his innate ability to articulate the most difficult physiological concepts in a manner any layman could understand taking examples mostly from his own experiences and also from everyday observations. He was the Professor of Physiology of the Faculty of Medicine, University of Colombo since 1982. He then became the Founder Dean of the newly established Faculty of Medicine of the University of Kelaniya at Ragama. He fervently assisted Professor Valentine Basnayake to inaugurate the Physiological Society of Sri Lanka (PSSL) on the 29th of May 1987 at the New Building Lecture Theatre of the Faculty of Medicine in Colombo. The Inter- medical Faculty Physiology Quiz organized by the PSSL among the medical students for the Carlo Fonseka Challenge Trophy is a tough competition. The trophy was generously donated by him. He immensely contributed to uplift the scientific principles at PSSL meetings as well as among a large number of undergraduate and postgraduate students, and followers of him. In his charismatic way, he was extremely successful in popularizing science and in particular, physiological principles among the general public. He was one of the most sought after speakers in any meeting on any topic ranging from science, physiology, medicine, music, songs, drama, philosophy, politics etc.  He was a prolific writer too.
Speaking at the A.C.E. Koch Birth Centenary Memorial Symposium held on the 20th of Nov 2003, Professor Fonseka quoted a eulogy written by an anonymous medical student about Professor A.C.E. Koch who is the first Sri Lankan Professor of Physiology and who is considered by Prof. Fonseka as his fairy godfather.

“…. He still lives with us. He is not dead – for to live in the hearts of those who truly love and revere is not to die”.

I am sure, this eulogy is equally applicable to the great physiological legend of our times, Professor Carlo Fonseka. The void created by the demise of this Physiological icon of Sri Lanka will never be filled.
