Florent Figon

I am an associate professor (Maitre de conférences in French) of Université Grenoble Alpes (UGA), working at the Laboratoire d'écologie alpine (LECA, UMR 5553 CNRS-Université Grenoble Alpes-Université Savoie Mont-Blanc, France) and the Institut national supérieur du professorat et de l'éducation (INSPÉ) 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.
