I study significant transitions in human history, specializing in the application of archaeological science to the study of collective social formations and the historical ecology of wetland and coastal environments. In the U.S. Atlantic and Gulf coasts, my recent research focuses on socioecological histories and zooarchaeological indicators to achieve high resolution, localized histories of human-climate dynamics. More broadly, my work centers on the nature of Indigenous governance by addressing cases that demonstrate the variability in the forms that democratic institutions might take. I am also engaged with NAGPRA (Native American Graves and Repatriation Act, to make sure that ancestors cared for by UGA are treated respectfully and repatriated to their descendent communities.
