My research and teaching interests are in demography, social inequality, immigration, and urban sociology. I have authored four books on these issues: Race and Ethnicity in America (2017), Portrait of America (2014), Poverty in America (3rd edition in 2013), and Where We Live Now: Immigration and Race in the United States (2009), all published by University of California Press. I have served as Co-Editor of the journal Demography and as elected Vice President of the Population Association of America.
