My research has meandered along the following lines: (1) How do people process (mis)information and what is the role of source crediblity and media trust? (2) How are political attitudes are affected by media exposure, specifically through web browsing? (3) What is the role of deliberation and represenation in achieving democratic outcomes? I have used data from online experiments, surveys, social media, trace data, and geospatial administrative data. Methodologically, I am interested in computational methods, measurement, causal inference, AI-based methods, and open science. Below, an overview of my publications (work in progress greyed out).
