Before joining UC Davis, Professor Wojcieszak was an associate professor of political communication at Amsterdam School of Communication Research, University of Amsterdam. Before that she worked at the IE School of Communication, IE University in Spain.

Professor Wojcieszak is interested in how the changing media environment creates both opportunities and challenges for informed publics, tolerant citizenry, and responsive governance. More specifically, she examines how media use and political talk affect opinion dynamics on both individual and societal level, and how these influence perceptions, knowledge, prejudice and tolerance, among other cognitive, attitudinal and behavioral outcomes relevant to diverse societies.

Professor Wojcieszak is the board member at large for Europe of the International Communication Association. She also serves as the editor of the International Journal of Public Opinion Research and on the editorial boards of Journal of Communication, Political Communication and EastBound electronic journal.

Her work has appeared in the Journal of Communication, Public Opinion Quarterly, Political Communication, Communication Research, Political Psychology, New Media & Society, among other journals.

Research Focus

Professor Wojcieszak’s research focuses on how people select political information in the current media environment and on the effects of these selections on attitudes, cognitions, and behaviors. She also examines the effects of mass media, new information technologies, and various message types on tolerance, perceptions, and polarization, as related to intergroup relations. Her current interests include ways to minimize selective exposure and biased information processing.
