Our main research interests concern the ‘Pigments of Life’, among them chlorophyll and vitamin B12: their discovery, their chemical and biological synthesis, their biologically important structure and chemical reactivity, as well as their biological functions, based on which, applications in the life sciences and in medicine are investigated. 


The Kräutler group is a founding member of the ‘Center for Molecular Biosciences Innsbruck’ (CMBI).
