I am a dual degree candidate at the Annenberg School and at the Department of Political Science at the University of Pennsylvania. My research focuses on information effects in politics, both on the aggregate and individual level. Specifically, I trace how political information spreads to from parties to citizens (through traditional and new forms of media as well as through informal interactions) and the conditions under which this information affects their attitudes and behavior.

My dissertation, entitled “Belief Echoes: The Persistent Effects of Misinformation and Correction” traces how exposure to misinformation can affect attitudes even after it is successfully corrected. Through a series of experiments, I find that a correction—even when it is fully believed—only reduces the attitudinal effects of exposure to negative information by about two-thirds. I call these lingering attitudinal effects “belief echoes.”
