On March 4th 2022, we kicked off our exciting new interdisciplinary project named CyanoBloom. We discussed science; how to efficiently share data, ideas and findings; we set goals for the first year; got to know each other and of course shared a great dinner and some drinks. There are four research groups with 14 team members and collaborators involved in this project. In the next four years, we will try to understand, why toxic cyanobacteria bloom. We are addressing the potential hypotheses about the mechanisms triggering cyanoHABs with a holistic and interdisciplinary approach. We are very excited to explore the world of CyanoBlooms and will keep everyone that is interested posted about it on this website.
