My research interests are marine macrophytes (seaweeds and seagrasses) and their interaction with microorganisms, mainly pathogens. I have conducted research in seagrass pathology where I investigated influence of environmental factors on host – pathogen interaction. Currently, my work focusses on diverse species of red algae - some of these with relevance in seaweed aquaculture – and their associated pathogens.
I am further interested in the process of seaweed domestication. I coordinate a global sampling campaign to assess the genetic resources of the seaweed commodity Kappaphycus and Eucheuma (red algae) to support a sustainable tropical seaweed aquaculture. This work is realised in close coordination with colleagues from Malaysia, the Philippines and the Republic of Tanzania.
