Research Interest

Our group studies the cellular and molecular mechanisms of synchronization within the mammalian circadian system. The suprachiasmatic nucleus (SCN) comprises the endogenous rhythm generator, integrating light information conveyed by the retinohypothalamic tract (RHT) and coordinates peripheral oscillators throughout the body. An SCN-intrinsic molecular clockwork drives rhythmic cellular properties and rhythmic output signals. Mice with a defect molecular clockwork show accelerated aging, disrupted metabolic homeostasis, and cognitive deficits.

Using conditional mice with targeted deletions of clock genes we are analysing the role of these transcriptional regulators for (I) hypothalamic regulation of feeding (II) glia-neuron interactions (III) adult neurogenesis and neuroregeneration (IV) synapse-formation and –function.
