Career


Research

Merrow is well known for her work on the entrainment of circadian clocks in both humans and the fungus
Neurospora crassa ''Neurospora crassa'' is a type of red bread mold of the phylum Ascomycota. The genus name, meaning 'nerve spore' in Greek, refers to the characteristic striations on the spores. The first published account of this fungus was from an infestatio ...

in simple systems. Her research focuses on oscillations at the cellular and molecular levels as a representation of organismal rhythms. Merrow's lab often uses techniques such as the insertion of Luciferase gene fusions or Green Fluroescent Protein to visualize oscillations of RNA levels, protein abundance, or protein modifications within the cell. Oscillations in the entrained phase can then be compared to the organism's free running period or the phase produced by other methods of entrainment to elucidate the mechanism of the clock.


Professional achievements

While she was a professor of Chronobiology at University of Groningen, Merrow led Sub-Project 4: Novel Clock Genes and Principles within EUCLOCK, a European organization of researchers interested in
entrainment Entrainment may refer to: * Air entrainment, the intentional creation of tiny air bubbles in concrete * Brainwave entrainment, the practice of entraining one's brainwaves to a desired frequency * Entrainment (biomusicology), the synchronization o ...
of circadian clocks. Merrow has served as the secretary and a member for the SRBR and is currently the vice-president of the European Biological Rhythms Society (EBRS). Merrow coordinated the OnTime consortium, a group consisting of Netherlands-based researchers in the field of chronobiology and is a member of the Program Committee for the upcoming XV EBRS Congress event to be held in Amsterdam. The group attempts to improve health through an understanding of circadian clocks and their entrainment. This consortium has its roots in Merrow's organization of the Dutch Clock Club, which is based on the structure of the UK Clock Club. She remains active in academia and has taught at the European Summer School for Chronobiology nearly every year since and including 1996. Additionally, Merrow strives to develop networks for women in science.
