Main research topics
Jacques is interested in the molecular and mechanical controls of plant morhogenesis. The structure and composition of plant cells have evlolved so as to make use of to the tensile forces generated by turgor pressure for shape.
Microstructural Theory of Wall Expansion: This aims to link the the microstructure of plant cell walls with mechanical properties. Cellulose microfibrils are thought to play a major role in determining the mechanical properties of the cell wall. By measuring mechanical strains associated with morphopgenesis we established that morphogenesis occurs isotropic in its plane
Mechanics of Tip Growth: we carry out work in a range of tip growing cells such as root hairs and pollen tubes to determine the constraints of tip growth.
Meristem Growth: we work on the mechanical deformation of the shoot apical meristem.
Morphological Evolution: we are interested in unravelling the the effects of multicellularity on morphological evolution.
