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 admission, retention, affirmative action and financial aid policies narrow these inequalities. I have published in leading journals in sociology, education and economics (including 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 has been supported by grants from the Spencer Foundation, the American Educational Research Association, the Russell Sage Foundation, and the Texas Higher Educational Opportunity Project.
I am currently writing a book-length manuscript that evaluates the ability of class-based affirmative action to promote the social and economic mobility of disadvantaged populations and boost diversity (geographic, economic and demographic) at selective postsecondary institutions, as compared with race-based policy. The book draws from within- and between-country (Israel, US) comparisons of several prototypes of affirmative action policy.
