Many organisms produce glowing light (often green in color) when exposed to a UV or blue light source. We study this phenomenon of fluorescence following two research topics:

1. We try to isolate the compound (molecules or proteins) able to convert the light from blue to green (but also other colors), which has attractive properties in biotechnology and biomedicine.
2. We also study the life history of the fluorescence and assess how it changes with stressful environmental conditions (related to climate change and/or chemical exposure). We therefore use the change of fluorescence as a proxy of organisms health in a change ecosystem.
