Dr. Rangika Hikkaduwa Koralege grew up in Sri Lanka and obtained her Bachelor of Science in chemistry from University of Kelaniya, Sri Lanka. She earned her Ph.D. in physical chemistry from Oklahoma State University, Stillwater, Oklahoma. Her doctoral dissertation was focused on investigating the oxidative behavior of fullerene colloidal suspensions in water to evaluate the potential health and environmental risks of fullerenes. Following doctoral studies, she joined the Department of Chemical Engineering at Oklahoma State University as a postdoctoral fellow to work on targeted delivery of therapeutic proteins using polymeric nanoparticles. She joined the Department of Chemistry and Physics at Western Carolina University in fall 2017. Her current research is focused on the synthesis and characterization of nanomaterials for biomedical applications and health and environmental impacts of water suspended fullerenes. She is a member of first-generation advocates at WCU. When not in the classroom or laboratory, she enjoys singing, listening to music, and baking.
