Pollack’s research covers three different fields: media and crime, journalism's role in the history of politics and political communication. Media and crime concerns the relationships between crime journalism and criminal policy, the interplay between several of society’s institutions, with symbolic and concrete significance when it comes to the legal system. Journalism’s role in the history of politics covers studies on Swedish news reporting about the Soviet Union in the 1930s and about the Holocaust during the Second World War period. In both cases she relates her research to the historical knowledge, reorientation and scientific debate about the course of events in the 1930s and '40s made during the past decade. Finally, her third area of research focuses on political communication: a) journalism and political scandals in the Nordic region, with publications Skandalenes Markedsplass. Politikk, Moral og Mediedrev , SCANDALOUS! The Mediated Construction of Political Scandals in Four Nordic Countries  and "Nordic Political Scandals: frequency, types and Consequences". In Ludwig, M., Schierl, T., & von Sikorski, C. (Eds.) Mediated Scandals - Gründe, Genese und von Folgeeffekte Mediale Skandalberichterstattung. 2016 and Pollack, E "Personalized Scandalization: sensationalizing trivial conflicts?". In Fugl Eskjær, M., Hjarvard, S. & Mortensen (Eds.),* The Dynamics of Mediatized Conflicts*  b) advocacy think tanks in the Nordic region with the publication ”Advocay Think Tanks as News Sources and Agenda Setters” in Politik (with Prof. Sigurd Allern)  c) public relations, journalism, politics and democracy. Among other things, she has studied lobbying as a political impetus and the importance of emerging journalistic cooperation for revealing corruption within international companies. In the field of political communication we have collaborated in a Nordic network of researchers.
