He is also a fellow at Harvard University’s Institute for Quantitative Social Science (IQSS), and at the NASA Tournament Lab. 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, network science, and computational social science, which he applies to investigating individual and collective decision-making, social media and social networks, and individual and team productivity. He also develops and applies novel computational approaches and machine learning to field and experiment data to study the design of contests and crowd-sourcing mechanisms.
