I research intergroup relations and conflict. In the past, I've studied discrimination based on gender, ethnicity, nativity, or race. Moving forward, I'm primarily focused on studying class-based discrimination. Growing up poor - without a home and then in a trailer park - taught me much about the role of class and money in politics and society.
Most of my work uses field or survey experiments and has focused on the United States or Japan but is increasingly expansive geographically, with new projects in South America, India, and the former Yugoslavia. Sometimes, I write about methodological issues related to experiments or measurement.
My research has been published or is forthcoming in over 30 journals or volumes, including the American Journal of Political Science, the American Political Science Review, the British Journal of Political Science (2), the Journal of Politics (2), Nature Human Behavior, Political Analysis, and the Proceedings of the National Academy of Sciences (2). This work has been covered by many media sources, such as National Public Radio's All Things Considered, Forbes, The Asahi Shimbun, The Atlantic, The Economist, The Guardian, The Huffington Post, The Washington Post, and Yahoo! News. It has also been cited in many policy documents, including U.S. House of Representatives testimony and State Department reports. I'm grateful to acknowledge funding from the American Political Science Association, Swedish Research Council, the Tokyo Foundation for Policy Research, and the Research Council of Norway.
