I am an Assistant Professor in the Department of Human Development at Cornell University. I am also in the Department of Government and on the graduate field faculty in Information Science.

I study politics and health, especially the social effects of government actions and how small groups of people adapt to sudden changes in their lives. My recent projects have studied the development of public attitudes toward the Affordable Care Act, how social networks heal after a death, and unintended consequences of online censorship in China.

My work has been published in the American Political Science Review, the American Journal of Political Science, the Journal of Politics, and the Proceedings of the National Academy of Sciences, among other outlets. It has also been covered in popular media, including The Atlantic, Science Magazine, The New York Times, the Los Angeles Times, and The Wall Street Journal.
