Eugene A. Hammel is internationally recognized for his work in social anthropology. In addition to studying social structure and kinship, his interests have included the statistical and formal analysis of social anthropological data. He has focused on peasant society and culture, particularly Balkan, and historical and anthropological demography. Hammel's fieldwork has been varied, from an investigation of Serbo-Croatian and Albanian kinship terminology among immigrants in California, to the patterns of consumption of alcoholic beverages among ethnic groups in the Southwestern United States. He has also researched Chiricahua and Navaho archaeology and social networks and mobility in urban locations in Yugoslavia. Hammel received his Ph.D. in Anthropology from the University of California, Berkeley in 1959. After holding a position as an Assistant Professor of Anthropology at the University of New Mexico, he joined the faculty in the Department of Anthropology at the University of California, Berkeley in 1961.
