Marcus P.S. Dekens obtained his Ph.D. in genetics (magna cum laude) at the Max-Planck Institute in Tübingen (Germany) under Prof. Christiane Nüsslein-Volhard (Nobel Laureate in Medicine 1995) where he took part in constructing the first radiation hybrid map of the zebrafish genome as well as a genetic screen for cell division and fertilization mutants, and demonstrated that the mutant futile cycle has a pronuclear congression (fertilization) defect. Thereafter he collaborated briefly with Prof. Nicholas Foulkes with whom he demonstrated that DNA replication is timed by light. After spending three years in the laboratory of Prof. David Whitmore, where he constructed a dominant-negative form of the clock gene as a tool to knock down the circadian clock and studied clock function, he moved for a short stint to the GeneCore facility of the European Molecular Biology Laboratory where he published the first zebrafish light-induced transcriptome and demonstrated how stress response and DNA repair genes are regulated by light. His current research activities focus on how light through the non-visual photoreceptor Melanopsin regulates activity levels during the wake state in the diurnal zebrafish. His main research interests are in non-visual light regulated processes covering neurogenetics, behavioural genetics, toxicology and chronopharmacology.
