Brief career history
Development of the fish inner ear
Summary for the non-specialist
Current projects in the Whitfield lab include:
Morphogenesis and patterning in the otic placode and vesicle
We are identifying pathways of gene activity that lead to correct axial patterning of the otic epithelium, together with establishment of the neurogenic, sensory and non-sensory domains in the developing ear. We have a long-standing interest in the roles that Hedgehog, Fgf and BMP signalling play in these processes.
Development of the vestibular system
The adult inner ear consists of three interconnected ducts of non-sensory epithelium—the semicircular canals—and various chambers containing sensory hair cells. We are examining zebrafish lines that develop with morphological defects of the semicircular canal system. We are using light-sheet microscopy to image semicircular canal formation in these lines, and automated tracking of adult fish to measure any balance deficits.

Inner ear epithelial cells are labelled in green, and actin is stained in red. The actin-rich hair bundles of the sensory hair cells form a bright red fringe on top of the crista, a band of sensory tissue at the base of the ampulla. Image credit: S. Baxendale and N. van Hateren. Transgenic line from Robert Knight.
Undergraduate taught modules
We welcome enquiries about opportunities for postdoctoral or postgraduate study in the lab. Any funding opportunities will be listed here when available, but we also welcome enquiries from postdocs who are interested in preparing fellowship applications (e.g. Marie Sklowodska-Curie Actions - Individual Fellowships).
