My main research topic is wood quality. I am mainly interested in round wood, from the standing tree in the forest to the sawmill. My activities are divided into two parts:

1. developing innovative methods for measuring wood properties;
2. modelling wood properties.
 

Regarding the first point, I mainly use X-ray or RGB image analysis. I am collaborating on this with a computer science research laboratory (Loria), and we are implementing traditional methods (e.g., TreeTrace project) as well as methods increasingly based on artificial intelligence such as CNNs and Vision Transformers (e.g., Biomtrace project). 

More recently, I have expanded my field of research to include biometric traceability of timber based on the analysis of photos of log cross-sections as part of a project with ONF and Loria (Biomtrace project).

On the second point, I collaborate with my colleagues who are specialists in growth modelling, as modelling wood quality depends heavily on growing conditions.

As part of the Baccfire project, I am working with ONF to classify tree species based on their anatomical, physical, architectural and ecological characteristics, among others. The aim is to form groups of species that are relatively homogeneous and can be used in generic modelling approaches, such as carbon flows in the forest-wood sector. Another objective is to identify species that are interesting in terms of both climate change resistance and wood quality.

For the link with the chemical properties of wood, I collaborate with Lermab (e.g., ExtraForEst project on the resource of forest extractives) and for the connection with the quality of sawn or peeled wood with colleagues from LaBoMaP in Cluny (e.g., TreeTrace project).
