Chen Pochan (Ph. D., Archaeology, University of California, Los Angeles) is Professor in the anthropology department at National Taiwan University. Originally interested in the possible problems of the original of the Austronesian language family, I changed my interest to the salt industry and distribution from the Neolithic period (ca. 3500 B.C.) to the Han Dynasty in the Three Gorges area, China. My current research project is a surface survey project in the Chengdu Plain, Sichuan Province, China. This is an international cooperation project with Chengdu Archaeology Team, Peking University, Harvard University, University of Washington, St. Louis, and UCLA. Through this project, we hope to understand the emergence of complex societies from the Neolithic Baodun Culture to the Bronze Age Sanxingdui Culture in the Chengdu Plain.
