Ellis Monk is an Assistant Professor in the Department of Sociology and a Faculty Associate of the Office of Population Research. He earned his PhD in Sociology from the University of California at Berkeley; and he taught at the University of Chicago before relocating to Princeton in Fall 2016. His research interests include: ethnoracial categorization and stratification; political sociology; health, theory; the sociology of the body; social psychology and cognition; and Brazil. Additionally, he is interested in Geometric Data Analysis (otherwise referred to as Multiple Correspondence Analysis). His research has been published or is forthcoming in the American Journal of Sociology, Social Forces, and Social Problems. My research focuses on the comparative examination of social inequality, especially with respect to race and ethnicity, in global perspective. This research uses both quantitative and qualitative methods, while drawing heavily upon contemporary theories of social cognition and categories. By deeply engaging with issues of measurement and methodology, it examines the complex relationships between social categories and social inequality; and extends into topics such as social demography, health, aging, social psychology, sociology of the body, political sociology, and comparative/historical sociology. In addition to working on a variety of projects that correspond to these areas of interest, I am also completing a book manuscript, which is the first comparative, mixed-methods examination of the social and economic significance of skin tone and hair as markers of ethnoracial division in the U.S. and Brazil. It illustrates how these markers of ethnoracial division determine differential treatment in intimate, commercial and public spheres alike. These findings are mined to contribute to current (and historical) debates on the foundations and lived reality of ethnoracial inequality in the Americas, "colorism" in global perspective, and theories of group formation.
