Giovanni Luca Ciampaglia
I am currently visiting postdoctoral fellow at the Center for Complex Networks and Systems Research (CNetS), Indiana University at Bloomington in the group of 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, and research associate at the Chair of sociology, in particular modeling and simulation, at the Swiss Federal Institute of Technology (ETH) in Zürich.
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 and my software developer portfolio.

02 Jul. 2012: I am the recipient of an SNF “Prospective Researcher” fellowship. Thanks to the financial support of the Swiss National Science Foundation, I will join the Center for Complex Networks and Systems Research, Indiana University, in early 2013.
12 Apr. 2012: Last December I successfully defended my Ph.D. thesis. The revised version is now online on this page. See below for the full reference information. UPDATE (24/04): The thesis is now available on RÉRO Doc.
10 Oct. 2011: Notabilia has been included for exposition at the Adobe Museum of Digital Media. You can find it here. The exhibit curator is Thomas Goetz, Wired.
01 Jul. 2011: I will spend two months at the Community department of the Wikimedia Foundation, doing research on the Wikipedia community.
10 Jan. 2011: Notabilia, a visualization of the longest AfD discussions on the English Wikipedia, is now public. Notabilia is a joint project with Moritz Stefaner (design and visualization) and Dario Taraborelli (data analysis and research). Notabilia has been featured on the Dutch magazine Bright Magazine, German magazine Page, on visualization blogs Infosthetics and Flowing data, and on technology blogs such as Boing boing and many more. Go have a look at it and… after that don't forget to wish Wikipedia happy birthday, because it's turning 10 soon!
04 Jan. 2010: I will be visiting Dirk Helbing's group at ETH Zurich for the next three months!
08-12 Jun. 2009: Attended the International Workshop on Coping with Crises in Complex Socio-Economic Systems (website), and presented my work on opinion dynamics and wikis. Slides are here in PDF format. A video of the talks is also available on videolectures.
01 Jul. 2008: Attended the Complex Systems Summer School 2008 at the Santa Fe Institute! Pictures are on Picasa.
