Dr.(Mrs.)W.G.Samanthi Konarasinghe, an award-winning Scientist has served as a Statistical Consultant and a Lecturer for more than two decades. She has developed various Mathematical and Statistical Techniques for the world. The Circular Model(CM), Circular Indicator(CI), and Sama Circular Model(SCM)are some of the widely applied techniques whilst the Damped Circular Model(DCM)and Forced Circular Model(FCM) are the recently developed models. The Circular Indicator was developed to measure the risk of returns of share market investments. The development of the CI was based on the motion of a particle in a horizontal circle (Newton’s law) and the philosophy of the Dharma wheel. The Dharma Chakra or "Wheel of Dharma" is a widespread symbol used in Indian religions such as Jainism, Hinduism, and Buddhism. The Circular Model was based on Newton’s Law of Circular Motion, Fourier Transformation, and Least Square Regression. The most important property of the CM is that the model could be applied for either stationary or non-stationary series. Further, the model is capable of capturing both seasonal and cyclical patterns of a time series. Yet the CM was applicable only for trend-free series, hence was improved later and named as the “Sama Circular Model”. The SCM is superior to decomposition techniques and Auto-Regressive Integrated Moving Average (ARIMA)/Seasonal Auto-Regressive Integrated Moving Average (SARIMA) in modeling wave-like patterns. However, the SCM also has limitations in modeling infectious diseases. Therefore Dr. Samanthi developed two new techniques, based on “Theory of Oscillations”.

Dr.Samanthi has won the Best Paper Award from the International Conference on Advances in Mathematics, Computers & Physical Sciences and the International Conference on Business, Economics, Social Sciences & Humanities for her research findings. She was awarded the“IMRF BEST SCIENTIST AWARD, INDIA” for her invaluable contribution to the field of Statistics. She has been in constant demand due to her new findings, getting invitations from various destinations to share her knowledge as the keynote speaker, invited speaker, etc. at international research forums in Thailand, Singapore, Malaysia, India, and Australia. Also, she was the guest of honor and the chief guest of many International research forums.

Dr.Samanthi is a multi-disciplinarian; has obtained a Bachelor of Science Degree in Mathematics; Postgraduate Diploma in Industrial Mathematics; Master of Science in Applied Statistics, Master of Business Administration (MBA), and Doctor of Philosophy in Statistics. Also has the Diploma in Classical Music. She is a member of; American Statistical Association (ASA), Statistical Society Australia (SSA), Institute of Applied Statistics, Sri Lanka(IASSL), and National Science Foundation(NSF), Sri Lanka. She is the Editor in Chief of, 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. Also an Editorial board member of the American Journal of Theoretical And Applied Statistics (AJTAS).

She is an Advisory member Technical/ Scientific Conference Committee member of the Scientific and Technical Research Association (STRA). Most interestingly, Dr. Samanthi is not only a Scientist but also an Artist; a Violinist, Painter, Writer, Drama producer, and Actress. The membership magazine of the American Statistical Association; “AMSTATNEWS” wrote two testimonials on her.
