His research addresses American national politics, especially the United States Supreme Court and macropolitical responsiveness and representation. His work on the Supreme Court deals principally with the interactions among the exercise of judicial power, judicial independence, and public opinion. His research on representation and responsiveness explores how dynamics in aggregate public opinion shape the decisions of national political institutions in the United States and how the choices made by institutions feedback into public opinion. Professor Ura’s research has been published in several leading political science journals, including the American Journal of Political Science, the Journal of Politics, Political Research Quarterly, and Political Communication.
