I am the Distinguished Professor of Sociology and Criminology at Penn State. My research and teaching interests are in demography, social inequality, and polarization in the United States. I have authored dozens of articles and five books on these topics, including Why We Disagree about Inequality: Social Justice vs. Social Order (2023), 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). I have taught classes on Social Problems, Social Demography, Poverty, and Immigration. I also served as Editor of the journal Demography and was elected Vice President of the Population Association of America.
