Benjamin E. Bagozzi

I am a Professor of Political Science & International Relations at the University of Delaware, where I run the Social Analytics Data Lab (SADL). I also serve as Associate Director of the university's Data Science Institute (DSI).

My research develops statistical and computational methods for political data that are flawed in systematic ways, such as inflated, underdispersed, misclassified, or underreported outcomes. I turn those methods into open-source software such as the R packages underdisp and iop, and help produce public datasets such as the UNFCCC Attendance Data and the POLECAT global event data. I apply these tools, along with text-as-data, network, and machine-learning approaches, to questions of political violence and state repression, climate and environmental politics, and government transparency and accountability. A growing line of my work studies the information environment itself: misinformation, state-linked manipulated media, and how large language models shape and evaluate political news.
