Our group aims to time cultural, environmental, and material changes in human history. We use radiocarbon dating and microarchaeological methods to build high-resolution chronologies of past events. We are interested in exploiting modern plants and archaeobotanical remains for past-climate reconstructions and develop new methods for radiocarbon dating of challenging materials. The center of the lab is the Dangoor Research Accelerator Mass Spectrometer system (D-REAMS).
