Research Projects

Regina DeWitt studies radiation in the environment and uses thermally (TL) and optically stimulated luminescence (OSL) for its detection. Dr. DeWitt’s group works in a wide variety of research areas, ranging from environmental, and medical, to planetary and space applications. The group investigates the properties of new materials and develops new luminescence instrumentation. A setup at the ECU accelerator is used to learn more about the basic physical processes of luminescence. They develop new techniques for accident dosimetry that will enable a faster response in case of radiation emergencies. They use TL and OSL to better understand the radiation environment in sediment and permafrost to study life in extreme environments. Dr. DeWitt’s TL/OSL Dating Laboratory accepts samples for sediment dating. Projects are ongoing at field sites in Antarctica and the Outer Banks in NC. Projects in the lab are both on the graduate- and undergraduate-level.
