Dirk Brockmann (Germany, September 2, 1969) is a German physicist and Professor at the Institute for Biology at Humboldt University of Berlin and the Robert Koch Institute, Berlin. Brockmann is known for his work in complex systems, complex networks, computational epidemiology, human mobility and anomalous diffusion. ==Career and Research== Brockmann studied physics and mathematics at Duke University and the University of Göttingen where he received his degree in theoretical physics in 1995 and his PhD in 2003. After postdoctoral positions at the Max Planck Institute for Dynamics and Self-Organization, Göttingen he became Associate Professor in the Department of Engineering Sciences and Applied Mathematics at Northwestern University in 2008. In 2013 he returned to Germany where he became Professor at the Institute for Biology at Humboldt University of Berlin. Brockmann worked on a variety of topics ranging from computational neuroscience, anomalous diffusion, Levy flights,〔Brockmann and Geisel. (Lévy flights in inhomogeneous media. ) Phys Rev Lett (2003) vol. 90 pp. 170601〕 human mobility, computational epidemiology,〔Hufnagel et al. (Forecast and control of epidemics in a globalized world. ) P Natl Acad Sci USA (2004) vol. 101 pp. 15124-15129〕 and complex networks. Brockmann pioneered the scientific use of mass data collected in online games in a 2006 study in which he and his colleagues analyzed the geographic circulation of millions of dollar-bills registered at the online bill tracking website Where's George? 〔Brockmann et al. (The scaling laws of human travel. ) Nature (2006) 439 pp. 462-465〕〔(Money-Circulation Science ), The New York Times Magazine - The 6th Annual Year in Ideas, 12-10-2006〕 This study lead to the discovery of universal scaling laws in human mobility, the forecast of spreading routes of the 2009 flu pandemic in the United States and effective geographic borders in the United States. Brockmann also pioneered the development of computational models and forecast systems for the global spread of epidemics based on global air-transportation. In a 2013 study Brockmann and his colleague Dirk Helbing showed that complex global contagion phenomena can be mapped onto simple propagating wave patterns using the theoretical concept of effective distance.〔Brockmann & Helbing (The Hidden Geometry of Complex, Network-Driven Contagion Phenomena ) Science 13 December 2013: Vol. 342 no. 6164 pp. 1337-1342〕 Tihs method was employed for import risk estimates during the Ebola virus epidemic in West Africa in 2014. Brockmann's research has been featured in an episode of the American crime drama television series Numbers. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dirk Brockmann」の詳細全文を読む スポンサード リンク
