Hiroki Sayama, assistant professor of bioengineering and Systems Science and Industrial Engineering, was invited as a guest scientist to the Max Planck Institute for the Physics of Complex Systems, Dresden, Germany, from July 23-Aug. 6. He collaborated with scientists at the Institute on research projects on complex adaptive networks. Two of his graduate students also accompanied him and engaged in research projects. Their travels were financially supported by the Office of International Science and Engineering at the National Science Foundation. In August, a poster presentation by Sayama and bioengineering undergraduate student Chun Wong, titled “Quantifying Evolutionary Dynamics of Swarm Chemistry” (https://mitpress.mit.edu/books/chapters/0262297140chap110.pdf), won the Best Poster Award at the Eleventh European Conference on Artificial Life (ECAL’11) held in Paris. Sayama’s poster was selected best by the audience’s votes out of 54 posters.
