The Corona crisis continues to affect worldwide travel.

As MacroScale participants are expected from all continents and an online event is not considered due to the many different time zones, the organisers and the scientific committee in dialogue with CCL have come to the decision to further postpone the 4th MacroScale conference originally announced for 2020.

We hope for your understanding and will keep you informed.
