As an archaeological anthropologist I am broadly interested in the ways societies shaped, and were shaped by, the landscapes they inhabited. My research is primarily focused on eastern North America, where I use methods that include geophysics, geoarchaeology, and chronological modeling to examine pre-Contact Native American landscape modification within the interconnected contexts of social, economic, and political institutions. My current research examines long-term human/landscape interactions across the Pinson Mounds landscape, as well as the shifting nature of landscape use within the urban context of Cahokia. I have conducted research on Late Archaic period (ca. 3000-1000 B.C.) hunter-gatherers in the Lower Mississippi Valley, Middle Woodland era (200 B.C.-A.D. 500) interaction and ceremonialism in the Ohio and Mississippi River Valleys, as well as on early forms of urbanism at the Mississippian site of Cahokia (ca. A.D. 1050-1350) outside present-day St. Louis, Missouri. I have also worked in the highland regions of Uzbekistan on Bronze Age, Iron Age, and Medieval pastoral communities. At CSU, I serve as founder and director of the CRAG (Center for Research in Archaeogeophysics and Geoarchaeology).
