Research Statement

Professor Reimer directs the Communication and Cognition Lab. The lab employs psychological methods to test theories about communication and decision making. Studies in the lab examine decision-making processes in individuals, social groups, and organizations. Professor Reimer's research program has the overarching goal to explore how communication principles facilitate decision making by guiding information processing and reducing information overload. Applied topics include the design of persuasive messages and risk communication.

Professor Reimer obtained a Ph.D. in Social Psychology from the Free University of Berlin and a Habilitation degree in Cognitive Psychology from the University of Basel in Switzerland. Before moving to the US, he worked as a research scientist at the Max Planck Institute for Human Development in Berlin (Germany). For his research and teaching, he received several awards including the College of Psychology's Award for Excellence in Research from the University of Basel in Switzerland, the Golden Anniversary Monograph Award from the National Communication Association, and the Dennis Gouran Award from the Group Communication Division of NCA. Professor Reimer served on the Board of Directors of INGRoup and chaired the Group Communication Division of NCA. In 2016, he was elected as incoming program planner and chair of the Social Cognition and Communication Division of the National Communication Association.
