Our goal is to understand how circadian clocks work and why they play such an important role in growth and stress responses. We study the regulation and role of circadian rhythms in plants and algae. Circadian rhythms are necessary for optimal growth and survival in several photosynthetic species, including Chlamydomonas rheinhardtii, Synechocystes sp. and Arabidopsis thaliana. Although circadian clocks share a basic architecture, they differ in their molecular components and appear not to be conserved between different taxa.

We work on the model plant Arabidopsis thaliana and have recently started analyzing rhythms in the heterokont alga Nannochloropsis oceanica.
