Born in Iran in 1985, Meysam Alizadeh received a BS and an MS in Industrial Engineering from Amirkabir University of Technology and an MS in Information Science from the University of Pittsburgh before joining George Mason University’s Computational Social Science PhD program in fall 2013. He received his PhD from GMU in 2016 and is a postdoctoral fellow at CNetS since September 2016 working under supervision of Professor Santo Fortunato.

Meysam’s research interests focus broadly around political extremism,opinion dynamics, social influence, and intergroup relationships. Methodologically, he integrates innovative information and communication technologies in political science, sociology, and policy analysis to study these interests. More specifically, he uses a mix of approaches ranging from agent-based modeling, Big Data analytics, social network and social media analysis, and text as data methods to explore various drivers of social influence, opinion change, and opinion extremism in the society.
