    Rodrigo Belo is a Researcher at the Heinz College, Carnegie Mellon University and at Católica-Lisbon, School of Business and Economics. His research focuses on the impact of technology in educational settings, and on the role of peer influence in product diffusion in very large social networks. He is also interested in the application of novel methods for identification of causal effects using observational data. His work has been published in top journal and peer-reviewed conferences such as Management Science and the IEEE Conference on Social Computing. Rodrigo holds a PhD in Technological Change and Entrepreneurship from Carnegie Mellon University, an MSc in Engineering and Public Policy from CMU, and a BSc in Computer Science and Engineering from Instituto Superior Técnico, Technical University of Lisbon.

  • Research

    I am a post-doctoral researcher at H. John Heinz III College, Carnegie Mellon University and Católica-Lisbon School of Business and Economics. My research interests lie on the economics of technology adoption and diffusion. I currently pursue two streams of research, namely on the Economic Impacts of ICTs in Education, and on Peer Influence and Product Adoption in Large Social Networks.

    Economic Impacts of ICTs in Education

    I am interested in the role of information and communication technologies (ICTs) in students’ learning experience, in how these technologies affect students’ educational outcomes and skill acquisition. I am also interested in the community level effects of providing students with these technologies, namely in terms of home Internet adoption and adults’ skills acquisition.

    Peer Influence and Product Adoption in Large Social Networks

    I am interested in quantifying the actual net effects of peer influence in large mobile and online social networks. Methodologically, identification of social influence in observational data is a difficult task, mainly due to phenomena such as homophily or other sources of correlation. I am interested in alternative methods to disentangle influence from these other effects.
