Video Lectures and Interviews
by Dr Kavan Ratnatunga

They have been chronologically listed below classified into few fields on which I have been videoed.
There are few mome videos in Sinhala, that has a separate list as most of that material is duplicated in these English Videos and I am clearly more articulate in English, rather than Sinhala.

With the 2020 March Covid-19 lock-down, many organizations switched to Zoom lectures and the number of recording of lecturers given increased dramatically. In 2022 October I decided to compile this list for easy access, as finding them on YouTube is not trivial.
