We use a combination of genomic and experimental approaches to study eukaryote genome evolution. Most of the work we do utilizes the fungal model system Neurospora (“the orange bread mold”) to challenge general evolutionary paradigms, but we are also expanding the work to include the model system Podospora anserina and non-model lichen species. We study questions such as the consequences of selection acting at multiple levels in the biological hierarchy, i.e., genes, nuclei and individuals, and what factors drive processes such as the evolution of sexual dimorphism.
