Research Theme

Our group works on the circadian clock that controls the rest-activity rhythms in the drosophila brain. We have three main research lines:- Neuronal bases of the brain clock: role of the different neuronal oscillators and organization of the network, light and temperature synchronization pathways (inputs), transmission of the circadian information in the brain (outputs)- Differentiation of the clock neurons and building of the circadian function during brain development- Molecular bases of the circadian oscillator: post-translational control of clock proteins (phosphorylation, ubiquitination, degradation) and search for new clock components through genetical and molecular approaches.
