On the 29th November to 1st December 2023, 25 MUST researchers and over 30 stakeholders attended the MUST kick-off in Lappeenranta, Finland.  During the kick-off researchers and stakeholders learnt about the major challenges facing each study area, and how MUST’s solutions could begin to address them. A big thanks goes to Anna Vouri and Terhi Jantunen from the City of Lappeenranta for helping organise this terrific event.
