A framework for studying the vulnerability of networks based on the theory of interdependent networks will be presented. In interdependent networks, such as infrastructures, when nodes in one network fail, they cause dependent nodes in other networks also to fail. This may happen recursively and can lead to a cascade of failures and to a sudden fragmentation of the system. I will present analytical solutions, based on percolation theory, for the critical thresholds, cascading failures, and the giant component of a network of n interdependent networks. I will show that the general theory of interdependent networks has many novel features that are not present in the classical network theory. I will also show that interdependent networks embedded in space are significantly more vulnerable compared to non-embedded networks. In particular, small localized attacks of zero fraction, but above a critical size, may lead to cascading failures that dynamically propagate and yield catastrophic consequences. I will also discuss the recent theory and experiments in interdependent superconducting networks where we identified a novel abrupt transition, although each isolated system shows a continuous transition.

These discoveries have impacted many other fields, such as medicine, biology, geophysics, and more. He has over 60,000 citations on ISI Web of Science and over 100,000 in Google Scholar. His h-index is 112 (142) in Web of Science (Google Scholar). Professor Havlin has been a Highly Cited Scientist in the last 3 years. He is a professor in the Physics Department at Bar-Ilan University. He received his PhD in 1972 from Bar Ilan University, and he has been a professor at BIU since 1984. Also, between the years of 1999 to 2001, he was the Dean of the Faculty of Exact Sciences, and from 1996 to 1999, he was the President of the Israel Physical Society. Professor Havlin is an IOP Honorary Fellow (England, 2021). He won the Senior Scientific Award of the International Complex Systems Society, the Israel prize in Physics (2018), Order of the Star of Italy, President of Italy (2017), the Rothschild Prize for Physical and Chemical Sciences, Israel (2014), the Lilienfeld Prize for "a most outstanding contribution to physics," APS, USA (2010), the Humboldt Senior Award, Germany (2006), the Distinguished Scientist Award, Chinese Academy of Sciences (2017), the Weizmann Prize for Exact Sciences, Israel (2009), the Nicholson Medal, American Physical Society, USA (2006), and many others. Professor Havlin has been a leading pioneer in the development of network science, with over 800 papers and books in the fields of statistical physics, network science, and interdisciplinary physical sciences. His main research interests in the last 12 years focus on interdependent networks, cascading failures, networks of networks, and their implications to real world problems. The real-world systems applications include physiology, climate, infrastructures, finance, traffic, earthquakes, and others.
