InterACt - one of 25 Leibniz-WissenschaftsCampi (as of 2020) - is a strategic initiative. As an interdisciplinary infection research network on the topic of 'Integrative Analysis of pathogen-induced Compartments', the ScienceCampus links existing research groups in the fields of infection research and structural biology in the Hamburg Metropolitan region even more closely. InterACt creates new structures and expertise for the integrative analysis of complex data sets in the long term. This research-driven network of Universität Hamburg and the Leibniz Institutes as well as other non-university research organisations, including EMBL and European XFEL, will provide a strong nucleus for further initiatives in the field of infection research in the medium term. The newly created research groups will play a major role in this.
