Final MICROCARD workshop and Cardiac Physiome meeting September 2024

The last MICROCARD workshop will be organized together with the annual meeting of the Cardiac Physiome Society, on 12 to 14 September 2024 in Freiburg im Breisgau, Germany. It will be part of a supercluster of events around MICROCARD hotspot Karlsruhe:

Stuttgart and Freiburg are a 45 minutes and 1 hour train raide away from Karlsruhe, respectively, so it's easy to attend all three meetings.

Thursday 12 September
