Adhitya Ronnie Effendie


Dr. Adhitya Ronnie Effendie is a lecturer and researcher at Actuarial Science Study program, Mathematics Department, Universitas Gadjah Mada (UGM) Yogyakarta. He was Chair of Statistics laboratory (2021-2022) prior to taking up a faculty position as Chair of Statistical Computation Laboratory at Mathematics Department FMIPA Universitas Gadjah Mada Yogyakarta (2022-present).

He was graduated from Mathematics Bachelor program, Institut Teknologi Bandung (ITB) in 1998. In 2002 he finished his Actuarial Science Master program from Rijks Universiteit Groningen (RuG) the Netherlands and in 2011 he completed his doctoral studies from UGM with his Ph. D thesis entitled “On Health Insurance Valuation Models with Dynamic Interest Rate using Multistate Risk Approach”.

His field of interests include computational Statistics, Statistical learning including machine learning and artificial intelligence, clustering and regression tree, computational Actuarial science, claim reserving, Risk theory and human mortality and morbidity modeling.


Research interests

Current research interests include application machine learning on claim reserving, claim modeling and non-life insurance’s tariff analysis. He also has some interests in health insurance, mortality and morbidity modeling and Long Term Care (LTC).
