The PCB Lab is focused on the intersection between political communication and political behavior. We study the nature of news and social media, and the effects that media have on our political decision-making. We rely on a range of social-scientific methods including surveys, automated content analysis, and psychophysiological studies. Recent work from lab members has examined platform-based differences in both sentiment and campaign communication, cognitive dissonance and selective exposure, valence-based biases in news consumption, and news coverage of political figures and policies.

PCB Lab members include current and past graduate students at UCLA and the University of Michigan:

• Current:
  • Mia Carbone, PhD student, Communication, University of California, Los Angeles
  • Guadalupe (Lupita) Madrigal, PhD student, Communication and Media, University of Michigan
  • Gavin Ploger, PhD student, Communication and Media, University of Michigan
  • Sydney Carr, PhD student, Political Science, University of Michigan
• Past:
  • Sarah Bachleda Fioroni, Research Consultant, Gallup
  • Dan Hiaeshutter-Rice, Assistant Professor, Advertising + PR, Michigan State University

I and my students are also members of the brand new, just starting (as of early 2022) Communication and Politics Group at UCLA.

I did not have a lab group while I was in the Department of Political Science at McGill University but I did have some terrific students, now doing excellent work all over the place: check out Kelly Blidook, Blake Andrew, Marc André Bodet, Andrea Lawlor, and Anthony Kevins.
