Prof David Whitmore
David Whitmore is Professor of Chronobiology in the UCL Research Department of Cell and Developmental Biology, and Centre for Cell and Molecular Dynamics.
He trained with Professor Gene Block at the University of Virginia, studying circadian clocks in the molluscs Bulla and Aplysia, before moving to the IGBMC in Strasbourg, where he was involved in the development of zebrafish as a model system for clock analysis.
The laboratory at UCL has continued to develop this system with the establishment of luminescent clock-containing cell lines, which allow for the dynamic imaging of rhythmic gene expression in living cells.

Our early circadian studies in zebrafish revealed several rather unexpected results. Initially, we were able to show that individual tissues within the adult contained their own independent circadian clock, and secondly, that these cells are themselves directly light responsive. This represented one of the earliest demonstrations of peripheral circadian organization. Since then, this observation has been extended to the earliest stages of embryo development, as well as to cells in culture.
This raises certain fundamental questions that our laboratory continues to explore. How do these cells and tissues directly detect light, and what general cellular processes does light influence? What is the central mechanism of this cellular clock, and what aspects of cell biology are controlled by the pervasive presence of a clock in each cell?
By employing a range of standard molecular techniques, retroviral approaches, and live cell imaging, we aim to explore how light and internal time measurement influence cell and neural physiology. Luminescent imaging allows us to see how the cellular clock changes dynamically in living cells as the levels of light and dark alter across the day. Similar approaches can be employed to follow changes in the regulation of downstream rhythmic events, such as the timing of cell division and activation of DNA repair.
In collaboration of Dr Yoshiyuki Yamamoto, we are also involved in field studies to explore how the fish circadian clock works under natural conditions in both rivers and cave complexes found in Northern Mexico.
