Hello! I am a Postdoctoral Fellow for the Polarization Research Lab at Stanford University. I received my PhD in Political Science at UCLA. My research interests lie at the intersection of political behavior and institutions, with a focus on representation. I am specifically interested in how partisan identification and animosity structures behavior across all levels of U.S. politics: national, state, and local. My current research aims to determine the degree to which national-level politics influence state/local-level decisions and quantify the consequences of such nationalization. I utilize methods involving big data, machine learning, text-as-data, and survey experiments. My work is published in the Proceedings of the National Academy of Sciences and the Quarterly Journal of Political Science, and has been cited in the New York Times. My dissertation and papers therein have been awarded the Christopher Z. Mooney Best Dissertation Prize and the SPPQ best paper award by APSA’s State Politics and Policy section.

Most recently, I worked as a research analyst for the UCLA COVID-19 Health and Politics Project, a collaboration between social scientists and doctors measuring people’s pandemic experiences and attitudes. Our work was featured in the New York Times and published in Vaccine. Previously, I was the project coordinator on Nationscape, a U.S. election survey that interviewed almost half a million respondents through the 2020 Presidential campaign. Nationscape was funded by the Democracy Fund.

Outside academia, you can find me trail/mountain/long distance running (from nothing in particular) and thanklessly rooting for the Seattle Mariners.
