Dr Ragel was appointed a Senior Lecturer in Computer Engineering at the University of Peradeniya in December 2007 and a Professor since October 2017.
He has been a Professional Member of the IEEE and IEEE Computer Society since 2005 and a Senior Member since 2014. He is also a Professional
Member of the Association of Computing Machinery (ACM).
Prof Ragel has co-authored almost 200 peer-reviewed articles in topics including System on Chip, Internet of Things,
Bioinformatics, Wearable Computing, and Digitisation of Local Language Text. He has won several best paper awards in
conference papers, the most prolific Sri Lankan author award from Elsevier Research in 2017 and the Presidential award for
scientific publication in Sri Lanka in 2018. He is also named the Top Scientist in Computer Science in Sri Lanka by AD
Scientific Index 2021 and 2022. With his present h-index of 23 (i10-index of 42), he is also recognised as a Tier 4* awardee
by the University of Peradeniya for Research Excellence under the Transparent Research Performance Scheme introduced by the
University Grants Commission (UGC) Sri Lanka. He was a visiting research scholar at the UNSW – Sydney, QUT – Brisbane, UIUC – Illinois
and ANU – Canberra.
Prof Ragel is also the consulting Chief Executive Officer at the Lanka Research and Education Network (LEARN),
the national NREN, since 2017. With his involvement, LEARN was able to step up for a significant milestone
by launching the Asi@Connect Project in Sri Lanka in 2017, which brings many opportunities for the LEARN Research
and Education (R&E) network community to get involved utilise the project resources and funds. He has represented
Sri Lanka in the Asi@Connect Governors meeting and has been a Council Member of Asia Pacific Advanced Network (APAN) since 2017. Since 2020, he is also the Vice-Chair of the Asi@Connect Steering Committee. With Covid-19 lockdowns, LEARN is helping the university community in the country connect and engage in productive research and education activities online. At the National level, Prof Ragel was a Core Group member for Higher Education at the Presidential Task Force for Education set up in 2020. He is a member of the UGC Standing Committee on the Development of IT Infrastructure and Online Education and UGC appointed committee to develop the Concept on Virtual / Hybrid University.
