Computational social scientist Mesysam Alizadeh is a postdoctoral researcher in the PRODIGI project. He has been harnessing the wealth of network and human social data available through social media platforms to understand the roots and spread of undesirable content and behavior. In projects during his Ph.D. at George Mason University and postdoctoral fellowship at Indiana University Bloomington, Alizadeh has explored the moral and emotional factors underlying political extremism. Meysam was a postdoctoral associate and associate research scholar at the Empirical Studies of Conflict Project at Princeton University, studying foreign influence efforts on democratic elections. In this project, advised by Professor Jacob Shapiro, Meysam used publicly available verified data sets of foreign online influence operations to train classifiers that can identify suspicious activities on social media. On September 2020, Meysam joined the Technology and Social Change team at Harvard University as a Data Science Fellow to work on domestic election interference operations on social media.
