At the threshold between disciplines, ISC-PIF serves as an intellectual interface between research organizations and higher education institutions. The Complex Systems Institute of Paris (ISC-PIF) is a place dedicated to the development of innovative and interdisciplinary research on complex systems at the crossroad between modeling, high performance computing and Big Data. It catalyzes, since 2005, the emergence of common and interdisciplinary practices, facilitating access to skills, work areas and pooled research resources. The residents of ISC-PIF, who are staff members and students employed by the institute or by a partner institution, work on projects that are hosted on-site. They are the first contributors to the activities and dynamism of ISC-PIF and the primary pillar to the thriving intellectual scene the institute seeks to shape.
