Alexander is a scientist at Nord. His research focuses on macroalgae and seagrass. His long-term research goal is to understand functional-trait variation at the molecular level and to apply this knowledge towards sustainable growth of economically important algae, and towards the management of kelp forests and seagrass meadows under the impact of climate change. Epigenetic research allows to understand trait variation and biodiversity from an entirely new perspective. He aims to apply this knowledge towards societally relevant questions related to coastal ecosystem management and protection in light of increasing human impact and to sustainable cultivation of kelp along Arctic shores.
