Sandra M. Florian joined the University of Pennsylvania in 2016 as a Postdoctoral Fellow in the Department of Sociology and the Population Studies Center (PSC). She obtained her Ph.D. in Sociology from the University of Southern California, and also holds a Masters in Urban Planning from the USC Sol Price School of Public Policy. In her research, Sandra uses demographic and statistical methods to study fertility, family, immigration, inequality and social mobility, and their intersections with race/ethnicity, class, and gender. Sandra's research has focused on identifying socioeconomic and demographic factors associated with family formation and fertility trajectories across racial/ethnic groups, and the ways in which fertility shapes women's employment, and broader patterns of social inequality. Another line of her research also explores the living arrangements, family structure, and patterns of multi-generational support in coresidential grandparent families in the U.S.
