Team BIOINFO is the GDEC bioinformatics platform. It also leads projects in the field of Triticeae genomics. We develop bioinformatics tools and pipelines to address the wheat genome complexity and we perform sequence analyses in order to improve of knowledge of wheat genome composition, organization, dynamics of transposable elements and their impact on wheat genome evolution and adaptation.
