Research topics and scientific interests
My research focuses on the taxonomy and systematic of lichens. I am using the combination of traditional taxonomical methods (morphology, microscopy, thin layer chromatography) with molecular phylogenetics, to understand the morphological and genetic variability of species. I am applying these methods to revise two complex genera of lichens: Usnea (Parmeliaceae), with emphasis on neotropical species, and species of the Peltigera canina complex (Peltigeraceae).

I am also involved in the study and monitoring of Swiss biodiversity: the checklist of Swiss lichens (in french), the development of a lichen flora of Switzerland, and several inventories, especially in the Jura region.
