Giovanni Luca Ciampaglia
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
and Paolo Giordano (co-advisor, Uni
Before joining CNetS, I was previously research analyst contractor at the
Wikimedia Foundation, working on editor
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.
