Dr. Karawdeniya earned her Bachelor of science, in chemistry and biological science, in Sri Lanka and earner her PhD in Chemistry from University of Rhode Island, United States in 2018. She joined the Department of Mechanical Engineering of Southern Methodist University, Dallas, Texas as a postdoctoral fellow. In 2020 she joined the Research School of Physics of Australian National University as a Research Fellow. Her research is in the cross fields of Chemistry, Physics, and Engineering. Dr. Karawdeniya is passionate about developing point-of-care sensors for health and environmental monitoring. Her major areas of interest are • metasurface optical sensors • solid-state nanopore single-molecule sensors • surface-enhanced Raman sensors • gas sensors • surface modification strategies Her expertise includes sensor platform development, surface chemical and physical modification, nanofabrication, and 3D design/printing. She is interested in the detection of biomarkers in biological fluids and volatile organic compounds in exhaled breath. Currently, Dr. Karawdeniya lead multiple research projects aimed at developing novel sensing technologies for health care monitoring. While being part of ARC CoE TMOS, she is also a part of the ANU Grand Challenge ‘Our health in Our Hands’ (OHIOH), a ANU research initiative aimed at bringing multiple disciplines together to develop new technologies for detection and monitoring of health conditions like diabetes. She is also the Program Coordinator of OHIOH Sensors.
