Curriculum vitae



Our research team analyses key regulatory transcription factors that control plant development. We conduct comparative approaches using plant model organisms such as Arabidopsis thaliana together with other evolutionary informative plant species. Current research focuses on the liverwort Marchantia polymorpha and the amphibious liverwort Riccia fluitans to unravel the role of redox-regulation in developmental processes and for an adaptation to a terrestrial plant life style.

Model  systems

  • Arabidopsis thaliana and angiosperms with interesting novelties such as flower symmetry
  • Marchantia polymorpha and Riccia fluitans
  • Additional informative water and land plants for comparative studies


  • Developmental genetics (genome editing, mutant analyses)
  • Expression analyses (mRNA, protein)
  • Transcriptomics (next generation sequencing)
  • Morphological studies
  • High resolution microscopy and redox sensors
  • DNA/protein interactions (EMSAs
