Dr. Walter’s research is centered on the intersection between classic media effects theories, and novel computational social sciences methods. His research addresses the ways computational methods such as network analysis, unsupervised machine learning and supervised machine learning can aid in the understanding of various political communication processes, with emphasis on election campaigns, international conflicts, the representation of foreign countries in news and entertainment media, online misinformation campaigns, and political extremism.
Among his current and recent research projects are: developing unsupervised machine learning approaches to frame analysis in traditional mass media and social media content (ANTMN), the impact of foreign actors’ online interference in US politics, the role of discourse structure in shaping public opinion, the conceptualization, measurement and impact of thematic diversity, strategies of political candidates on twitter, impact of news framing on candidates electoral success, representation of foreign countries in US media, and Far-right extremism in online platforms.
