Przemyslaw Grabowicz


I am a postdoc researcher in The Max Planck Institute for Software Systems under the supervision of Krishna Krishna Gummadi.

Main topic of my research is analysis of online social networks. Although I have Master in physics, the research which we perform with my collaborators is truly interdisciplinary, on the frontier between computer science, sociology, and physics. I have conducted my PhD studies at the Institute for Cross-Disciplinary Physics and Complex Systems in Palma de Mallorca under the supervision of Víctor Eguiluz and José Ramasco.
 
I have a feeling that my journey with social networks is just spinning off. I had a pleasure to participate in Truthy project at Indiana University, where we developed its real-time movies feature, which later won WICI Data Challenge. More recently, I finished a half year long internship at Yahoo! Research Barcelona in the Social Media Engagement Group and joined MPI-SWS.
