Responsible DS+AI Speaker Series: Milena Tsvetkova

Milena Tsvetkova is an assistant professor in the Department of Methodology. She completed her PhD in sociology at Cornell University in 2015. Prior to joining LSE in 2017, she was a postdoctoral researcher in computational social science at the Oxford Internet Institute, University of Oxford. Tsvetkova's research interests lie in the fields of computational and experimental social science. She employs online experiments, network analysis, and agent-based models to study fundamental social phenomena such as cooperation, contagion, and inequality. Her current work investigates the structural conditions under which inequality emerges and worsens when individuals interact in large social groups. In collaboration with computer scientists, physicists, organizational scientists, and game developers, she is working on incorporating gamification to develop new methods for large-scale social interaction experiments online.
