circle2018I am a paleobotanist working on the systematic and functional diversity of Paleozoic and early Mesozoic plants (-400 to -200 millions years). Since 2011, I am a permanent C.N.R.S. Research Scientist in the department “Botanique et Bio-Informatique de l’Architecture des Plantes“, in Montpellier, France.

Je suis une paléobotaniste qui travaille sur la diversité systématique et fonctionelle des plantes du Paléozoïque et du début du Mésozoïque (il y a environ 400 à 200 millions d’années). Depuis 2011, je suis Chargée de Recherche au CNRS dans l’UMR “Botanique et Bio-Informatique de l’Architecture des Plantes” de Montpellier.

Taxonomic and functionnal diversity of plants during the Paleozoic and early Mesozoic.

I work on pre-angiosperm floras  from the Paleozoic and early Mesozoic (-400 to -200 millions years ago), with a special interest for fossil trees and for plants from the supercontinent Gondwana –the southern continents of today.  My research objectives revolve around three complementary lines of investigation:

(1) Systematics: we use morphological and anatomical characters of fossil plants to document past systematic diversity and understand the origin and diversification of key groups of plants.

(2) Fossil plant biology: we combine morpho-anatomical evidence from fossils with data on extant plants to reconstruct different functionnal traits (growth habit, architecture, sprouting ability, hydraulic and mechanical properties, etc.)

(3) Processes underlying plant diversity: we investigate how evolutionnary and paleoenvironmental factors (climate, geography, biological crises, …) impact the systematic and functionnal diversity of plants through time.
