Edwige joined the group in April 2011 as a Junior Research Fellow (Queens' College) and Marie Curie Post-doctoral Fellow following a PhD at the University of Grenoble and the Ecole Normale Supérieure of Lyon, France. She is currently a Herchel Smith Fellow and a Bye-Fellow at Queens’ College.
Her doctoral research focused on the properties of the LEAFY gene, a central regulator of flower development, which is also linked with the emergence of flowering plants.
Her current work aims at understanding how living organisms can produce iridescence. Iridescence is generated by the interaction of light with minute structures organized on or just below the surface of plants and animals, thus creating visible colours that are independent of chemical pigments but we know nothing about the development and patterning of these nanostructures. In flowers, the iridescent effect is due to ordered striations (like those on a CD) of the cuticle on the petal epidermis and pollinators can use this iridescence as a cue to detect flowers. To understand how and when these nanostructures develop, Edwige combines biomechanical modeling and optics with modern genetic analysis, live-tissue imaging and behavioural ecology, using Venice Mallow (Hibiscus trionum) as a model species. With this project, she hopes to discover original developmental pathways, used by flowering plants to shape their surfaces and communicate with insects.
