David Garcia

Senior Researcher

Complexity Science Hub Vienna and Medical University of Vienna



David Garcia is a faculty member at the Complexity Science Hub and Group Leader at the Medical University of Vienna since September 2017. He leads a research group funded by WWTF (Vienna Research Groups for Young Investigators Call). He holds computer science degrees from Universidad Autonoma de Madrid (Spain) and ETH Zurich (Switzerland). David did a PhD and Postdoc at ETH Zurich, working at the Chair of Systems Design. His research focuses on computational social science, designing models and analysing human behaviour through digital traces. His main work revolves around the topics of affect and political polarization, combining statistical analyses of large datasets of online interaction with agent-based modeling of individual behaviour. His PhD thesis “Modeling collective emotions in online communities” provides an example of how agent-based modeling can be used to construct an integrated approach to collective emotional phenomena in cyberspace. His Postdoctoral research on opinion polarization and online privacy has been funded by the Swiss National Science Foundation and the ETH Risk Centre. David’s work lies at the intersection of various scientific disciplines, combining methods from network science, computer science, and statistical physics to answer questions from psychology, economics, and political science.
