Dr. Panagiotis Karampourniotis, Research Assistant in the Center, advised by Prof. Gyorgy Korniss and Prof. Boleslaw Szymanski, defended his Ph.D. thesis in Physics titled "The Impact of Heterogeneity in Thresholds of Opinion Dynamics and in Crowd Decision-Making". In the thesis, Dr. Karampourniotis analyzed how recent global events and their poor predictability are often attributed to the complexity of the world event dynamics. A key factor generating the turbulence is human diversity. Here, he studied the impact of heterogeneity of individuals on opinion formation and emergence of global biases. In the case of opinion formation, he focused on the heterogeneity of individuals' susceptibility to new ideas. In the case of global biases, he focused on the aggregated heterogeneity of individuals in a country.
