Przemyslaw A. Grabowicz

I am a postdoctoral researcher in The Max Planck Institute for Software Systems in the social computing group headed by Krishna Gummadi.

The main areas of my research are computational social science and social computing. These areas are truly interdisciplinary, on the frontier between computer science, sociology, and physics. Among others, I am interested in collective social phenomena such as social influence, information diffusion, and opinion formation.
