Plant ecological genomics
Plant Genome Evolution and Diversification
Despite evidence pointing to gene duplication, transposition and epigenetic changes going along with plant diversification, the evolutionary significance of such genome dynamics remains elusive. Our work thus integrates evolutionary ecology and genomics to better understand speciation and adaptive radiation under changing environments.
Our projects often (but not only) use polyploid speciation as a model process integrating genomic and ecological changes. They combine high-throughput genomic technologies with experimental and empirical field studies to untangle the genetic and ecological drivers of diversification in alpine and Mediterranean plant populations.
