Emily K. Vraga joined the faculty at George Mason University in 2012 as an assistant professor in the Department of Communication. She received her Ph.D. at the University of Wisconsin-Madison in the School of Journalism and Mass Communication and spent one year as a Post-Doctoral Research Instructor in the School of Media and Public Affairs at George Washington University.
Dr. Vraga's research focuses on how individuals respond to news and information about contentious political, scientific, and health issues, particularly when they encounter disagreement with their views via digital media. I am especially interested in (1) using news media literacy messages to limit biased processing and improve news consumption habits, (2) detecting and correcting misinformation via social media, and (3) encouraging attention to more diverse political content online. I prioritize using diverse methodologies - such as eye tracking, experiments, surveys, content analysis, and in-depth interviews - to better match an evolving media environment.
