Ecological Genomics of Ectomycorrhizal Fungi

I am passionate about evolutionary biology and how organisms interact with their environment. In particular, I have a keen interest in studying local adaptation of populations in forest and alpine ecosystems. How and why the tree of life maintained complex mating systems is also a facet of biology that fascinates me. Using genomic tools and high-resolution environmental descriptors, I dedicate my research activities to improve our understanding of (co-)adaptation processes in plant-fungi symbiotic partners.
