Complex Spreading Phenomena in Social Systems (eBook)

Sune Lehmann is an associate professor at the Technical University of Denmark, an adjunct (full) professor at the University of Copenhagen’s Department of Sociology, and and adjunct associate professor at the Niels Bohr Institute for Theoretical Physics. He’s also associate director of the interdisciplinary "Center for Social Data Science" at the University of Copenhagen. In addition to publishing in top interdisciplinary journals, Prof Lehmann’s work on spreading processes —  including spreading in both biological and social domains — has received world-wide press coverage.Yong-Yeol (YY) Ahn is an assistant professor at Indiana University School of Informatics, Computing, and Engineering. He worked as a postdoctoral research associate at the Center for Complex Network Research at Northeastern University and as a visiting researcher at the Center for Cancer Systems Biology at Dana-Farber Cancer Institute after earning his PhD in Statistical Physics from KAIST in 2008. He has made contributions in a variety of areas including the study of network community structure, information diffusion, and culture. He is a recipient of several awards, including the Microsoft Research Faculty Fellowship and the LinkedIn Economic Graph Challenge.
