Personnel Information:

He was elected as Member of the European Molecular Biology Organisation (2001), Associate Member of the Class of Sciences of the Royal Academy of Belgium (2006), Fellow of the Royal Society, London (2007), Member of Academia Europea, UK (2009), Member of the German Academy of Sciences Leopoldina (2009), Member of National Academy of Sciences, USA (2012). He studies the mechanisms by which the developmental programmes of annual and perennial plants are synchronised to the changing seasons. Arabidopsis thaliana is a model annual species and he has shown how circadian-clock regulation of transcription of specific regulatory genes and photoreceptor signaling combine to promote flowering of this species in response to long summer days. This process activates expression in the leaf of a protein that
moves systemically to the shoot meristem and reprogrammes transcription leading to flower development. Perennial relatives of A. thaliana show interesting differences in their responses to seasonal cues, and we have developed Arabis alpina as a model perennial. This species flowers predominately in response to winter cold, and shows characteristic features of perennials such as only becoming sensitive to environmental cues after it reaches a certain age and transitioning between episodes of flowering and vegetative development within its life cycle. Using a combination of forward genetics and genomics we have defined some of the mechanisms by which floral transition differs between annuals and perennials, contributing to the divergence of these life histories during evolution.
