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 at the state and local levels of U.S. politics. 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 Quarterly Journal of Political Science, provisionally accepted at the Proceedings of the National Academy of Sciences, and has been cited in the New York Times.

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.
