I study plant developmental mechanisms using integrated approaches that combine functional genetics, imaging, and modeling. Within the DIADE research unit, my work aims to improve our understanding of the regulatory networks that control the formation and activity of root meristems, and their contribution to plant architecture, physiology, and adaptation.
