About

Markus Strohmaier is a Full Professor of Web-Science at the Faculty of Computer Science at University of Koblenz-Landau (Germany), Founder and Scientific Director of the Computational Social Science department at GESIS - the Leibniz Institute for the Social Sciences (Germany), and a Distinguished Visiting Scholar at Stanford University's Media-X program (since 2010). He has been a visiting scientist/professor at Stanford University (USA) during the 2011/12 academic year, at XEROX Parc (2009, 2010-2011) and at RWTH Aachen (2009). Markus Strohmaier received his PhD from the Faculty of Computer Science at Graz University of Technology in 2004. From 2006-2007, he was a Postdoctoral Fellow at the Dept. of Computer Science at University of Toronto working with Prof. Eric Yu on agent-oriented and social modeling. In 2012, he completed his habilitation at Graz University of Technology. His main research interests include Web-Science, Social and Semantic Computing, Social Software Engineering, Networks and Data Mining. To date, he has been awarded substantial research funding (either as PI, Co-PI or key scientist) from national and European funding agencies. He teaches computer science courses both on an undergraduate and graduate level and has taught classes with more than 200 students. One of his courses was nominated for an Excellence in Teaching award by Graz University of Technology. Markus Strohmaier has published in top-tier conferences and high impact journals including the International World Wide Web (WWW) conference, the International Semantic Web Conference (ISWC), the International Conference on Web and Social Media (ICWSM), ACM Hypertext, the ACM Conference on Information and Knowledge Management (CIKM), the IEEE Conference on Social Computing (SocialCom) as well as the ACM Transactions on Intelligent Systems and Technology (ACM TIST), the Information Processing and Management Journal and IEEE Intelligent Systems.
