The Max Planck Institute for Infection Biology (MPIIB) is a non-university research institute of the Max Planck Society located in the heart of Berlin in Berlin-Mitte. It was founded in 1993.[1] Arturo Zychlinsky is currently the Managing Director.[2] The MPIIB is divided into nine research groups, two partner groups and two Emeritus Groups of the founding director Stefan H.
