My main research interests include social stratification and mobility, with an emphasis on the sociology of education. My work focuses on discovering the dynamics and historical processes underlying class, gender, and racial-ethnic inequalities in higher education, and the extent to which do admission, retention, affirmative action and financial aid policies narrow these inequalities. My perspective is interdisciplinary, taking into account educational processes and outcomes, institutional arrangements and social structures, as well as demographic contours and trends. I am an active member of the American Educational Research Association, American Sociological Association, and the Population Association of America and I have publications in several leading journals in sociology, education and economics (including the American Sociological Review, Social Forces, Work and Occupations, Sociology of Education, Economics of Education Review, Research in Higher Education, and Social Science Research). My research was supported by grants from the Spencer Foundation, the American Educational Research Association, the Russell Sage Foundation, and the Texas Higher Educational Opportunity Project.
