Postdoc position (m/f/d) | Multiscale, multiphysics, mathematical modelling of plant morphogenesis

Job Offer from January 23, 2026

The Research Group Mathematics and mechanics of plant morphogenesis at the Max Planck Institute for Plant Breeding Research in Cologne is seeking to fill a Postdoc position (m/f/d) in multiscale, multiphysics, mathematical modelling of plant morphogenesis as soon as possible.

Plant growth is a complex hydromechanical process in which cells enlarge through water uptake, while their walls expand and remodel under turgor-driven tension. In multicellular tissues, where cells are mechanically interconnected, morphogenesis emerges from the combined effects of local growth processes, shaped by heterogeneous mechanical, physical, and chemical fields that act with varying degrees of non-local influence. From a mathematical perspective, this constitutes a multiphysics problem that is typically multiscale. A rational understanding of plant morphogenesis, therefore, requires dedicated mathematical approaches.

At the cellular scale, computational models provide insight into the complex dynamics of individual cell growth and water transport within tissues [1]. At the tissue scale, we have developed a continuum theory of plant growth that treats tissue as a poromorphoelastic body—a growing poroelastic medium in which growth arises from pressure-driven deformations and osmotically driven water uptake [3, 5]. At the scale of an organ, such as a shoot or a root, differential growth generates large macroscopic deformations that alter the posture of the organ. Here, dimensional-reduction-based methods can help elucidate the overall dynamics of plant motion [2, 4].

In this project, the candidate will be expected to explore a range of fundamental and applied problems in mathematical modelling of plant morphogenesis based on these approaches. Depending on their preferences and abilities, this work may involve more numerical or analytical aspects.
