Question: How can digital media increase our ability to mobilize successful collective responses to time-critical emergency situations?
Group Leader: Manuel Cebrian
We live in a world beset by an increasingly diverse and unpredictable array of threats. From terrorism to biological weapons, climate-change disasters to crowd panics, energy blackouts to cyber-attacks, these challenges reverberate across interconnected global networks, with their many benefits (e.g. speed of communication, potential for collaborative responses) and problems (e.g. hacking, malicious surveillance, disinformation).
The Digital Mobilization Research Group, led by Manuel Cebrian, investigates new ways to understand how digital technologies can enable crowdsourced intelligence for responding to and mitigating the impact of such threats. The research group studies these questions using tools from Network Science and Computational Social Science, with particular emphasis on advanced data-driven modeling and simulation tools.
