Andrew Tiedt (Ph.D. 2011) is a postdoctoral fellow at the Center for Demography and Economics of Aging at the University of Chicago. His research examines gender differences in depression among the elderly in Japan and the United States, focusing especially on the how exchange with family, and other types of social support, can protect against or exacerbate depression. An article based on this research was published in the Journal of Cross-Cultural Gerontology (2010).
