I am an anthropological archaeologist engaged in research on Northeast Asia. The majority of my research has been on the prehistory and proto-history of the Korean Peninsula in the period 3500 BC - AD 300. My PhD dissertation is about patterns of storage and social change in Mumun Period Korea (c. 1500-300 BC). I am interested in how and why the earliest socio-politically complex polities formed, particularly from the perspective of agriculture, settlements, and political economy. I was most recently a member of the excavation team of the Pyeonggeo-dong site in Jinju, Korea from 2006-2012 and the Chojeon-dong site in 2011 and 2013. I am a member of the Early Korea Project Steering Committee at Harvard University and a member of the editorial board of the serial publication, Early Korea. I am also the Korea representative of the Society for East Asian Archaeology (SEAA).
