About Me

I am currently assistant research scientist at the Indiana University Network Science Institute. I work on information diffusion in close collaboration with Filippo Menczer and Alessandro Flammini.

I obtained my Ph.D. in Informatics from Università della Svizzera Italiana (also known as University of Lugano) in December 2011. My research was supervised jointly by Luca Maria Gambardella (IDSIA), Alberto Vancheri (co-advisor, SUPSI) and Paolo Giordano (co-advisor, Uni Wien).

Before joining CNetS, I was previously research analyst contractor at the Wikimedia Foundation, working on editor engagement issues, research associate at the Chair of Computational Social Science, in the Swiss Federal Institute of Technology (ETH) in Zürich, Switzerland, and SNSF postdoctoral fellow at the Center for Complex Networks and Systems Research (CNetS), Indiana University Bloomington, thanks to the generous support of the Swiss National Science Foundation.

My research is about collective social phenomena on the Internet, in particular large-scale collaboration platforms such as Wikipedia. I am also interested in other complex social phenomena such as emergence of social norms, cultural dynamics. Prior to my Ph.D. studies I also worked on models of urban growth. You can find more information in my curriculum vitae, complete list of publications, and my (old) software portfolio.
