Presentation

I am an associate professor (*Maitre de conférences* in French) of *Université Grenoble Alpes* ([UGA](https://www.univ-grenoble-alpes.fr/english/)), working at the *Laboratoire d'écologie alpine* ([LECA](https://leca.osug.fr/?lang=en), UMR 5553 CNRS-Université Grenoble Alpes-Université Savoie Mont-Blanc, France) and the *Institut national supérieur du professorat et de l'éducation* ([INSPÉ](https://inspe.univ-grenoble-alpes.fr/)) of Grenoble. I am deeply interested in understanding organismal biology with an integrative approach, i.e. at a multiscale and interdisciplinary level. My research at the **Alpine Ecology Laboratory** focuses on the **ecophysiology of pigmentation** in insects, particularly on the link between global change (temperature and metal pollutants) and pigments (ommochromes, pterins and melanins) of butterfly wings. By deciphering the **structural and functional diversity** of wing pigments along **thermal and urban gradients** in the Alps, the aim is to provide a better understanding of how animals can adapt to human impacts on their ecosystems. This project is deeply **interdisciplinary**, with methods ranging from quantum chemistry to correlative Synchrotron-based and electron imaging.[](https://social.sciences.re/@ffigon)
