The Center for Social and Biomedical Complexity (CSBC: https://csbc.sice.indiana.edu) at Indiana University Bloomington is accepting applications for one or more full-time non-tenure track postdoctoral fellows to conduct interdisciplinary research in Complex Networks and Systems applied to various social, ecological, biological, medicine and health problems. The expected start date for the appointments is February 2020. Candidates interested in conducting research in urban community-environment systems, or network science methods to analyze and visualize information relevant for epilepsy and other chronic diseases are encouraged to apply. The appointments are full-time for 12 months, with potential to be extended an additional year subject to funding and satisfactory performance. We offer a competitive salary with generous benefits. The postdocs will join a dynamic and interdisciplinary team that includes systems scientists, biologists, computer scientists, and social scientists. The postdocs will work with Prof. Luis M Rocha (https://informatics.indiana.edu/rocha/) and Prof. Johan Bollen (https://informatics.indiana.edu/jbollen/).
