I’m interested in quantitative eco-anatomy, a discriminatory method that differentiates wild plants (growing under natural conditions) from cultivated plants (growing under the influence and control of man) through comparative measurements of wood structural and vascular elements. My working models are grapevine (Vitis vinifera L.), olive (Olea europaea L. ssp. europaea var. europaea) and argan (Argania spinosa (L.) Skeels. To gain a better understanding of the long and complex history of viticulture, I regularly complete a reference collection of charcoal from actual vines (wild and varietal), which serves as a benchmark for comparison with archaeological material of different periods from sites in the Midi. My work on olive and argan trees is linked to the adaptation of these two species to climate change. I’m also interested in the dissemination of vine and olive pollen. I’m also involved in monitoring a wild vine population in Pic St Loup (TO-VITIS, OSU-OREME).
