The First IMBB Alumni Community reunion successfully took place on October 20 2023. Together with present members of IMBB we celebrated the 40 years anniversary of IMBB. Presentations ranging on subjects from science to personal memories, from remembering those no longer with us to the history of IMBB, gave us the opportunity to link up with the past and present of our diverse community. During coffee breaks and poster session we met up with old friends and connected with new ones. In the evening, we all had dinner together and our special DJ played music that got many participants on the dance floor. It was truly a day to remember for the many that participated. And we all agreed that we will meet again!
