    Interests

    Study of circadian rhythms in the mammalian suprachiasmatic nucleus (SCN) using genetic, imaging, transcriptomic and electrophysiological approaches. My primary research focuses on the role of GABAergic and neuropeptidergic signalling within the SCN and how astrocytes and neurons contribute to the network-wide coherence of circadian rhythmicity. Additional projects include the manipulation of organotypic SCN slices using pharmacology and optogenetic approaches.
