Precise timing is ubiquitous and of great importance for physiology and behavior. Indeed, biological timing includes diverse time-related mechanisms that encompass several orders of magnitude, from microsecond processing to seasonal rhythms.
In the Laboratory of Chronobiology we study biological timing, with special emphasis on two temporal scales: circadian timing and time estimation in the seconds-to-minutes range.
Circadian timing refers to the range of the 24-h, and governs a large array of physiological, metabolic and behavioral functions. In mammals, the circadian clock is located in the suprachiasmatic nuclei (SCN) of the hypothalamus. Most – if not all – organisms exhibit daily and circadian rhythms with periods of ca. 24-h, which also serve as the basis for seasonal-encoding mechanisms and might be related to lifespan-related processes. In the seconds-to-minutes range, interval timing is involved in a number of fundamental behaviors such as foraging, decision-making and learning, via activation of cortico-striatal circuits.

Research lines

  • Signaling pathways involved in photic synchronization of the mammalian circadian clock.
  • Interactions between the circadian system and the immune system.
  • Role of glia in the intercellular communication.
  • Analysis of behavioral and metabolic variables through the development of animal models with circadian disorders.
  • Assessment of risk factors and sleep – wake cycle in different populations at risk.
  • Temporal processing in the seconds-to-minutes range: interaction with the circadian system.
  • Daily variations in decision making.
  • Circadian rhythms in Caenorhabditis elegans.
