Biological pattern formation and morphogenesis

Description of current projects: Pairing transcriptomic with morphometric data to explore the regulation of morphogenesis. Studying phenotypic variation, due to genetic and environmental origins, during the dynamics of embryonic development from a whole gene expression and morphological point of view.

Collaborators: Patrick Lemaire, Ed Munro, Alexander, Aulehla
