I am a post-doctoral fellow at the Center for the Study of Race, Ethnicity, and Immigration at the University of Pennsylvania.

I received my PhD in September 2021 from the Politics Department at New York University. 

I study how changes to public policy and representation impact political behavior in the context of the United States, with a substantive focus on education and criminal justice. My work applies causal inference and experimental methods to examine how changes in institutional racial diversity and resource allocation impact racial disparities in crime victimization, partisanshipideology, and voter turnout

My job market paper examines how exposure to people of color during adolescence affects the racial attitudes and partisanship of non-Hispanic whites well into adulthood. To do so, I link web-scraped social media data with voter registration files and find that as white students' high schools became less racially diverse, they were significantly more likely to identify as Democrats twenty years after graduating.

My scholarly work has been published in Public Choice and has also appeared in Vox. Before entering graduate school, I was a middle school English teacher in Istanbul. I graduated from the University of Michigan in 2015, with a B.A. in Political Science and Middle East and North African Studies.
