Computational social scientist Meysam Alizadeh is a senior 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 postdoc fellow at Indiana University Bloomington, Alizadeh has explored the moral and emotional factors underlying political extremism. Meysam was an associate research scholar at the Empirical Studies of Conflict Project at Princeton University, studying foreign influence efforts on democratic elections. 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. His current research, advised by Prof. Fabrizio Gilardi, focuses on framing theory, application of LLMs, and content moderation.
