Before joining Northeastern in 2013, he was a postdoctoral fellow at Harvard Business School and the IQSS. Professor Riedl’s research interests are data analytics and computational social science, which he applies to investigating individual and collective decision-making, social media and social networks, individual and team productivity, and the Web as a platform for service innovation. He also develops and applies novel computational approaches and machine learning to field data to study the design of innovation contests and crowd-sourcing mechanisms.
