Dear colleague, We are very happy to announce that the GESIS Computational Social Science Winter Symposium http://www.gesis.org/en/events/css-wintersymposium/ will take place on Dec 1st in Cologne, Germany. This will be a one-day event consisting of: (i) an exciting program featuring a series of invited talks that will provide different perspectives on current advances and limitations of computational social science. (ii) an open call for contributed posters that will provide opportunities for computational social scientists to present and discuss their own work and (iii) an evening event at the famous Cologne Christmas markets that will provide plenty of opportunities for further discussions and informal networking. The program will feature lectures from the following invited speakers (all confirmed): Prof. Dirk Brockmann (HU Berlin) Prof. Frank Schweitzer (ETH Zürich) Prof. Andreas Diekmann (ETH Zürich) Prof. Harald Schön (U. Mannheim) Assistant Prof. Sophie Mützel (U. Luzern) Dr. Ciro Cattuto (ISI Turino) Dr. Suzy Moat (U. of Warwick) Please consider attending or forwarding this announcement to your students / members of your group. I'd be excited if this were an opportunity to meet and discuss current computational social science research in Cologne in December. with best wishes, Markus Strohmaier -- Prof. Dr. Markus Strohmaier Scientific Director, Computational Social Science GESIS - Leibniz Institute for the Social Sciences phone (office): ++49-221-47694-401 address: Unter Sachsenhausen 6-8, 50667 Cologne, Germany Professor of Web-Science, University of Koblenz-Landau address: Universitaetsstr. 1, 56070 Koblenz, Germany
