Research Abstract

My laboratory seeks to understand the organization, regulation and outputs of circadian neural circuits in the Drosophila brain. We take advantage of the remarkable molecular genetic methods that are available with this model system. Our principal contributions include (i) identifying roles played by the PDF neuropeptide and its receptor: We have analyzed its role genetically, demonstrated it to be a synchronizer of the molecular clock in individual pacemaker neurons under constant conditions... read more
