Seth Holmes holds the Martin Sisters Endowed Chair in UC Berkeley's School of Public Health. A physician and anthropologist who studies immigration and health, he is the author of Fresh Fruit, Broken Bodies: Migrant Farmworkers in the United States (UC Press, 2013). In researching this book, Holmes migrated with undocumented indigenous Mexicans in the U.S. and Mexico, picked berries and lived in a labor camp in Washington State, pruned vineyards in central California, harvested corn in the mountains of Oaxaca, accompanied migrant laborers on clinic visits, and trekked across the border desert into Arizona An article from this work has been awarded the Rudolf Virchow Award from the Society for Medical Anthropology. Holmes is currently conducting research into the processes through which medical trainees learn to perceive and respond to social difference. In addition, he is exploring new interdisciplinary research into the social, cultural and political processes producing high HIV death rates among specific groups of people, notably Latino day laborers and other ethno-racial minorities, homeless people and sexual minorities. This new project addresses the ways that political economic structures and social categories affect individual behavior and vulnerability.
