Marius Janson is a Professor of Management Science and Information Systems in the School of Business Administration, and Fellow in the Center for International Studies, the University of Missouri-St.Louis. He received his Master of Science (1977) and Ph.D. (1982) degree in Qualitative Analysis and Management Information Systems from the University of Minnesota.

Professor Janson's primary research interest is the impact of informatization on worklife. He is presently conducting a field study of a large Belgian discount chain. The project, a collaborative effort with a faculty member of the Katholieke Universiteit Brabant, uses Habermas' communicative action theory to investigate and interpret the quality of worklife and the shifting power relationships between upper management and company employees.

Professor Janson's other research interests include the role of information technology in the emerging free market economies of Eastern European countries, and the application of speech act theory to information analysis and knowledge acquisition. He has presented his research at international conferences organized by the International Federation for Information Processing (IFIP) and the Institute for Operations Research and the Management Sciences (INFORS).

A Fellow in the Center for International Studies, Professor Janson helped create a student exchange program between Hoge School Holland, Amsterdam, The Netherlands and the University of Missouri-St.Louis.
