My name is Christoph Riedl and I am assistant professor for Information Systems at Northeastern University. I hold appointments at the D’Amore-McKim School of Business and the College of Computer & Information Science. I am core faculty at the NULab for Texts, Maps, and Networks. I am also a fellow at the Institute for Quantitative Social Science (IQSS) at Harvard University and a fellow of the NASA Tournament Lab. Before joining Northeastern University I was a post-doctoral fellow at Harvard Business School and IQSS. I received a PhD in Information Systems from Technische Universität München (TUM), Germany in 2011, a MSc in Information Systems in 2007, and a BSc in Computer Science in 2006. My work has been published in leading journals such as Communications of the AIS and International Journal of Electronic Commerce, and conferences including the International Conference on Information Systems (ICIS).
My research interests are in data science and computational social science which I apply to substantive research questions on decision making by individual (peer-review), decision making by groups (collective intelligence), social media and online social networks, individual and team productivity, and the Web as a platform for service innovation. I apply and develop novel computational approaches and machine learning to (experimental) field data in order to study the design of innovation contests and various crowd sourcing / collective intelligence mechanisms. For example, I investigate various aspects of team formation and team work in competitions for creative workers. In my research on collective intelligence, I consider ratings, rankings, expert reviews, and online consumer reviews to support decision making.
