My research and teaching interests are in gender, labor markets, social inequality, employment discrimination, and quantitative methods. The primary goal of my research is to identify sources of inequality in labor market and institutional processes. The U.S. economy has undergone profound structural changes over the past half-century, such as deindustrialization, technological change, and demographic changes in the workforce. These changes have transformed how work is organized, but also have unevenly affected workers, depending on their social status. My research identifies new forms of inequality introduced by these changes using large-scale data and advanced statistical techniques.

One of my primary project explores effects of the rising long work hour (“overwork”) on many forms of gender inequality. Other projects explore how other characteristics of the changing economic environment (e.g., increased job mobility and diffusion of flexible work arrangements) affect labor market inequality between men and women and between parents and non-parents. Other related research projects examine the institutional bases of rising income inequality, and organizational and legal processes that improve workplace equality.
