Major K. M. Udaya Banda Konarasinghe, an award-winning Scientist has served as a Research Consultant and a Lecturer over the last decade. He is a distinguished researcher in the fields of, Tourism & Hospitality Management; Econometrics; Biological & Healthcare research. He is an expert in Time Series Modelling and Forecasting and made an unparalleled contribution to combating the COVID-19 pandemic.
He is an entrepreneur, who has taken initiative to the Institute of Mathematics and Management, Sri Lanka which provides a unique service in Education and Research. The Sama Circular Model (SCM) is a recent development in the field of Stochastic Modelling. The SCM is capable of capturing all the components (Trend, Seasonal, and Cyclical) of a time series with the least effort. Especially the SCM separates many seasonal and/ or cyclical behaviours in a time series. It had been widely applied in the fields of Finance, Economics, Tourism & Hospitality, etc., and has proven its superiority among other statistical forecasting methods. Yet the SCM had never been applied in the field of Epidemiology until Major Udaya does in modelling COVID-19 infected cases. He showed that the SCM is the most successful technique in forecasting daily infected cases in many countries. Further, he identified a damped and forced type of oscillations in the time series of infected cases under the COVID-19 pandemic. Hence in 2021, Major Udaya and his fellow researcher developed two new forecasting techniques, named “Damped Circular Model and Forced Circular Model”. Major Udaya won the Outstanding Paper Award at the 14th International Conference on Business Management (ICBM), University of Sri Jayawardanapura of Sri Lanka in 2017.
He was invited to share his knowledge and experience as the keynote speaker at international research forums in Germany, Dubai, and Italy and several sessions chaired in Thailand. He is the Editorial Manager of, the Journal of New Frontiers in Mathematics & Statistics; Journal of New Frontiers in Economics & Business; Journal of New Frontiers in Healthcare & Biological Sciences; Journal of New Frontiers in Education & Social Sciences, published by the Institute of Mathematics and Management of Sri Lanka. He is a Reviewer of the International Journal of Statistics and Mathematics, Premier Publishers, Nigeria, Banwa Series B.
