Current topic of research :

Cheese is a fermented food product that is the result of the transformation of milk by a variety of microorganisms. Two Penicillium fungi are used for the maturation of cheese :

  • Penicillium roqueforti, the blue mould, used for producing blue cheese
  • Penicillium camemberti, the white mold, used for the production of Camembert-type cheese.

We use comparative genomics to understand the genetic basis of parallel adaptation of these two species to cheese.

We also use population genomics to unravel the history of domestication of Penicillium roqueforti.
