Academic Career and Research Areas

Prof. Pfeffer’s research focuses on the analysis of large and dynamic socio-technical systems as well as the methodological, algorithmic and theoretical challenges that arise from these analyses. Pfeffer's research falls at the intersection of social and computer sciences. Current projects deal with the modeling and detection of negative dynamics in social media, such as online firestorms and hate against politically active women.

After ten years of professional experience in NGOs, consulting firms and non-university research institutions, Jürgen Pfeffer acquired a doctorate in business informatics at the University of Technology in 2010. He subsequently worked as a postdoctoral fellow at Carnegie Mellon University (USA) until he was appointed there as Assistant Research Professor in 2012. Since March 1, 2016, Prof. Jürgen Pfeffer has been serving as Professor of Computational Social Science & Big Data at the Bavarian School of Public Policy at TUM.
