Our research focuses on the genetics of the circadian clock and seasonal timing, particularly natural genetic variation, population genetics and molecular evolution of clock genes. We look for variations that serves as adaptations in different environments. Drosophila is our main model organism, but other models, including human are also used. We also study the molecular basis of photoperiodic timing that represents largely uncharted territory within the field of chronobiology. We also interested in the genetic of diurnal/ nocturnal activity preference, and the role of the gut microbiome.
