Duminda S. Ranasinghe was born and grew up in Sri Lanka. He received a bachelor's degree in science from the University of Kelaniya, Sri Lanka and bachelor's degree in chemistry from the Institute of Chemistry Ceylon, Sri Lanka. After completing the bachelor's degree in chemistry, Duminda worked as a teaching assistant and a part-time lecturer in mathematics in the Institute of Chemistry Ceylon for one and half years.
In fall of 2011, Duminda joined the Ph.D. program in chemistry at Wesleyan University under the advice of Prof. George A. Petersson where he worked on the development of CBS-Wes, a compound model chemistry method, a successor to CBS-QB3. Duminda was involved in the construction of nZaPa, and nZaPa-CV basis sets where n=2..7. The purpose of nZaPa family basis sets is to have the same error per electron when moving from left to right of the periodic table plus perform a systematic extrapolation of energy to the CBS limit. During the Ph.D. at Wesleyan, Duminda proposed and developed a density functional to calculate the missing core-valence correlation energy in Frozen Core Coupled Cluster Calculations.
After finish Ph.D. in September of 2015, Duminda starts working as a post-doctoral research associate in the Quantum Theory Project with Professor Rodney J. Bartlett at the University of Florida, Gainesville. At the University of Florida, Duminda worked on a density functional theory, focusing on developing a density functional which satisfy a correlated orbital theory (COT); an exact single particle method which includes correlation energy of electrons.
At fall of 2018, Duminda joined Green group, where he focuses on automating quantum mechanics calculations to obtain thermochemical parameters to improve kinetic modeling of fuel combustion. Duminda is am an amateur photographer and during a free time like to watch movies.
