He received his PhD in sociology from Harvard in 2017. He studies racial inequality in the United States. He focuses in particular on labor-market inequality: how the spatial organization of urban labor markets creates racial inequality in access to employment; how organizations mediate racial inequality in exposure to environmental pollutants; and how organizational hiring and promotion practices affect diversity in those organizations. He also studies mass incarceration, another institution with racial inequality at its core. Finally, he develops novel statistical methods for causal inference, record linkage, change-point analysis, and covariance regression.
