ACTSYS: Anticipating critical transitions in networked systems

Critical transitions, abrupt qualitative changes of system states, are common and pivotal behaviors of complex systems such as collapses of communities in ecosystem, onsets of severe droughts in moderate climate, and market crashes in global finance. Generally it is extremely difficult to foresee that a system is approaching such transitions. Recently slow recovery from perturbations near a critical transition have been suggested as generic indicators of early warning signals for critical transitions.

However, these indicators have been mostly considered in homogeneous systems such as population of yeast and zooplankton which lack the complexity of structurally and dynamically heterogeneous systems. Indeed, complex systems such as social networks, financial markets, transportation, or Internet are interwoven by complex networks. The ACTSYS aims to identify how networked systems response to perturbations near critical transitions for anticipating critical transitions in networks.


Young-Ho Eom obtained his BSc (2002), MSc (2004), and PhD (2009) in physics from KAIST, South Korea. He conducted his post-doctoral research on complex systems, collective behaviors, and network theory at Institute for scientific interchange, Turin, Italy from 2009 to 2012, at Laboratoire de Physique Théorique (CNRS), Universite Toulouse, France from 2012 to 2014, and at IMT Institute for advanced studies Lucca, Italy from 2014 to 2015, respectively.

His primary research interest is mathematical analysis and modeling of complex systems and collective behaviors in nature and society. He is an expert on complex network theory, mathematical modeling of collective behaviors and complex systems, and data analysis of social-information systems. Currently he is exploring how abrupt changes can happen and propagate in networked systems thanks to support of the CONEX program.
