Ethnographer Stacy Torres, assistant professor at the UC San Francisco School of Nursing, is shedding a unique light on how we think about social ties and social relationships among older people – how places affect social interactions, particularly in areas where gentrification is changing the character of neighborhoods. In addition to publishing in academic journals and mainstream periodicals, including the New York Times and San Francisco Chronicle, Torres is also working on a book examining social relationships among older people experiencing aging-related changes.
