BrieAnna Langlie

Associate Professor



Langlie's research is focused on the origins and long-term sustainability of agricultural systems and foodways. She specializes in paleoethnobotany and landscape archaeology in the Andes Mountains of South America. She has recently been studying how terraced fields, cropping schemes, and food systems were tuned to warfare and climate oscillations for a large community living in the hinterlands near Lake Titicaca between AD 1100 and 1450. She is also involved in ongoing and collaborative research on agricultural terraces, and the biological and cultural processes of domestication of Andean crops such as potatoes and quinoa.
