Xinyi Liu

Xinyi Liu is a Professor of Archaeology and Associate Chair of the Department of Anthropology at Washington University in St. Louis. She holds a PhD from the University of Cambridge. Her research focuses on plant domestication, agricultural origins, and prehistoric food globalization, with a particular emphasis on millet and the prehistory of China. She leads fieldwork projects across the Tibetan Plateau, Hexi Corridor, Inner Mongolia, Central Asia, and Eastern Europe.

Her work bridges archaeology with environmental science, using stable isotope analyses, archaeobotanical methods, and geospatial modeling. She is affiliated with the Laboratory for the Analysis of Early Food-Webs (LAEF), which examines nutrition-ecology interactions in diverse environments including the Tibetan Plateau and the Lower Yangtze region. Dr. Liu serves on editorial boards for journals like Environmental Archaeology and Archaeological Research in Asia and chairs the International Work Group for Paleoethnobotany.

Her recent studies highlight millet's ecological significance and its role in achieving modern food security. Her publications (2020-2024) analyze prehistoric crop management strategies, animal domestication genetics, and the socio-environmental impacts of early food globalization. These works emphasize East Asian contributions to global prehistory and the interplay between ancient culinary practices and biodiversity.

Dr. Liu's lab collaborates internationally, combining bioarchaeological data with modern ecological insights to address contemporary sustainability challenges. She has advised numerous graduate students and contributes to courses on environmental archaeology, bio-molecular approaches, and culinary globalization's deep history.
