K. D. R. Jagath-Kumara received the BSc (1985), MEngSc (1992), and PhD (1997) degrees from the University of Peradeniya, Sri Lanka, the University of New South Wales, Australia, and the University of South Australia respectively. He was with the University of Oslo in Norway for two semesters in 1990. Jagath-Kumara was employed as an engineer in the Ceylon Electricity Board from 1986-1987 and in the Airports and Aviation Services (Sri Lanka) Ltd from 1987-1989. He was a research fellow at the University of South Australia from 1996-97 and was a lecturer in the Massey university, New Zealand from 2000-06. From 2006, he has been a senior lecturer in the University of Peradeniya, Sri Lanka. Jagath-Kumara is the author of the book titled “Basics of Network Engineering” and has published 9 journal papers. He has also published 23 papers in the proceedings of international conferences and four papers in local symposiums/research sessions. He has presented papers at 19 international conferences and given 6 international seminars. Further, he has given presentations at four local research sessions/symposiums. He has served as a member, co-chair or the chair of the TPC for many international conferences and has reviewed close to 100 journal and conference papers. In the past, he was engaged in doing research on hybrid-ARQ, HF radio links, channel modelling and statistical signal processing.
