Early communications between China and other East Asian and Southeast Asian countries, particularly through the study of archaeological ceramics.

The study of interregional relationships among East and Southeast Asian countries through archaeological materials of the last two thousand years has filled in many details about those societies. I have initiated and/or participated in a number of field projects studying ancient ceramic industrial sites in China, Korea, Japan and Thailand. I have also done excavations at early seaport sites in Thailand and Indonesia, where imported ceramics were traded and used. The results have helped to explain the evolution of local economies and interregional trade. I have also conducted research on ceramic ethnoarchaeology aimed at understanding technology and industrial organization in less developed communities of the present day.
