Diana Z. O'Brien

Professor of Political Science

I am a Professor in the Department of Political Science at Washington University in St. Louis.

My research and teaching focuses on the causes and consequences of women's political representation in established democracies — including Western Europe and the United States — and across the globe. In particular, I study gender and political parties, legislative and executive branch politics, citizens' responses to women's presence in politics, and research methods.

I have published articles on these topics in journals including the American Political Science Review, American Journal of Political Science, Journal of Politics, and Politics & Gender. News coverage of my work has appeared in The Washington Post, The Guardian, Newsweek, MSNBC, Newsweek, FiveThirtyEight, Vox, Ms. and multiple international outlets.

My research has been awarded the Midwest Political Science Association's Sophonisba Breckinridge Award for the best paper on the topic of women and politics, the Journal of Elections, Public Opinion and Parties best article award, and the American Political Science Association's Lawrence Longley Award. My work on women and security portfolios is currently supported by the National Science Foundation (SES-1851457).

I am also an active member of the broader gender and politics community. I am the founding editor of the Cambridge University Press Elements in Gender and Politics Series, a founding member of the EGEN network and have been an associate editor at Politics & Gender, president of the Midwest Women’s Caucus, executive board member of the APSA Women, Gender, and Politics Research Section,.
