Using Friends as Sensors to Detect Global-Scale Contagious Outbreaks

Authors: Manuel Garcia-Herranz, Esteban Moro, Manuel Cebrian, Nicholas A. Christakis and James H. Fowler Journal: PLoS ONE 9(4): e92413 (2014) LINK SummaryRecent research has focused on the monitoring of global–scale online data for improved detection of epidemics, mood patterns, movements in the stock market political revolutions, box-office revenues, consumer behaviour and many other important phenomena. However, privacy considerations and the sheer scale of data available online are quickly making global monitoring infeasible, and existing methods do not take full advantage of local network structure to identify key nodes for monitoring. ...

Talk in "Mathematics of Social Learning"

I was recently invited to give a talk in the workshop entitled “Mathematics of Social Learning” which took place at the Institute of Pure and Applied Mathematics in UCLA, Los Angeles. Here is the program in which you can also find the recorded videos of the talks. May talk entitled “Are you a social keeper or a social explorer” about our research on communication strategies was recorded too. Enjoy!

Performance of Social Network Sensors During Hurricane Sandy

Authors: Yury Kryvasheyeu, Haohui Chen, Esteban Moro, Pascal Van Hentenryck, Manuel Cebrian Journal: PLoS ONE 10(2): e0117288 (2015) LINK Summary Information flow during catastrophic events is a critical aspect of disaster management. Modern communication platforms, in particular online social networks, provide an opportunity to study such flow, and a mean to derive early-warning sensors, improving emergency preparedness and response. Performance of the social networks sensor method, based on topological and behavioural properties derived from the “friendship paradox”, is studied here for over 50 million Twitter messages posted before, during, and after Hurricane Sandy. ...
