In recent years part of my research has been focused on the cyanobacterial neurotoxin BMAA in respect to occurrence and spread of BMAA in our environment. We are also focused on getting information on the function and regulation of BMAA in cyanobacteria. In addition, I have a research projects on cyanobacteria in association with mosses - covering research areas from the cyanobacterial biodiversity and host specificity to communication between the two partners and how the colonization is being controlled by chemical signals.
