I am a professor of Government and of African and African-American Studies at Harvard University, where I also serve as the Director of Graduate Studies for the Department of Government.

My research and teaching interests are in the fields of American political behavior, public opinion, and race and ethnic politics. My research has considered the effects of descriptive representation on political engagement and citizens' orientations toward their government; how neighborhood environments shape racial and political attitudes among Black Americans; the roots of competition and cooperation between minority groups, with a particular focus on relations between Black Americans and Latinos; and the effects of majority-minority districting on legislative responsiveness. My current research projects include a study evaluating the consequences of assisted housing mobility programs for political participation among the poor, drawing on evidence from the federal Moving To Opportunity demonstration program; a collaborative book project with Jennifer Hochschild (Harvard) and Michael Jones-Correa (Cornell) on the topic of immigrant political incorporation; a collaborative project with Jennifer Hochschild (Harvard) examining the effects of survey context on the measurement of linked fate; and a longitudinal study of macro-partisanship among Black Americans.

Before joining the Department of Government in September 2006, I was an assistant professor of political science at Stanford University from 2000 to 2005, and an associate professor from 2005 to 2006. From 1999 to 2000, I was a Visiting Fellow at the Public Policy Institute of California where I conducted research and published a monograph that examined voter participation in minority-dominated congressional districts. I earned my PhD from the Department of Government at Harvard University in 1998 and was awarded the department’s Toppan Prize for the best dissertation in political science. I earned a Bachelor’s degree in Economics from Stanford University, where I graduated in 1992 with Honors and Distinction and was awarded the Anna Laura Myers Prize for the best senior thesis in Economics.
