Networks with complex topologies describe systems as diverse as the cell or
the World Wide Web. The emergence of these networks is driven by
self-organizing processes that are governed by simple but generic laws.
Analysis of the metabolic and protein network of various organisms
shows that cells and complex man-made networks, such as the Internet or
the WWW, share the same large-scale topology. The underlying
inhomogeneous structure of these complex webs has important consequences
regarding their robustness against failures and attacks, with simultaneous
implications for drug design and our ability to defend the Internet from

Albert-László Barabási is the Emil T. Hofman Professor of Physics at the University of Notre Dame. Born in Transylvania, and educated in
Bucharest and Budapest, he received a PhD in physics in 1994 from
Boston University. After spending a year at IBM's T.J. Watson Research
Center he joined the Notre Dame faculty in 1995. His research has led to the
discovery and understanding of scale-free networks, describing many
complex networks in technology and nature, from the World Wide Web to
the cell. His current research focuses on applying the concepts
developed by his group for characterizing the topology of the WWW and
the Internet to uncover the structural and topological properties of
complex metabolic and genetic networks. He is the author of the recent
general-audience book Linked: The New Science of Networks (Perseus,
2002). For more information see http://www.nd.edu/~alb.
