Main scientific topics

1. Biomecanics: Study of the mechanisms allowing uprighting of trees from macro scale to macromolecular level.

- Mechanical behaviour and uprighing of sapling and adult trees in tropical rain forest

- Systematic anatomy of tension wood in tropical species

- Relationship between wood structure and growth stresses at the cell wall level

- Maturation stress generation in trees: study of the mechanism inducing tension in cellulose during cell maturation

- Development of the gelatinous layer in tension wood

2. Structure / properties relationship in wood: consequences of reaction wood on wood quality.

- Physical (drying shrinkage) and mechanical properties (growth stresses, MOE) of tension wood in relation with anatomy and ultrastructure (cellulose organisation)

- Microstructural determinants of viscoelasticity in wood and wood cell wall

- Consequences of growth stresses on drying

- Microscopic origin of drying shrinkage in tension wood

- Microcaracterisation of wood cell wall (microfibril angle, mesoporosity, sorption, composition)

- Traditional use of wood in building by ancient communities of French Guiana
