Mesysam has been harnessing the wealth of network and human social data available through social media platforms to understand the roots and spread of extremist ideology. In recent projects during his Ph.D. at George Mason University and postdoctoral fellowship at Indiana University Bloomington, Alizadeh has explored the moral and emotional fac-tors underlying political extremism. He is also studying how extremism spreads on social media by analyzing the information sharing behavior of political extremists on Twitter. Currently, Meysam is a postdoctoral research associate at the Empirical Studies of Conflict Project at Princeton University and is studying foreign influence efforts on democratic elections.
