Overview

I am a molecular cell biologist with interests in cell polarity, cell morphogenesis and the cytoskeleton. My research focuses on how eukaryotic flagella/cilia are built, and how this goes wrong in human inherited disease. I am particularly interested in the early stages of ciliogenesis: centrosome migration and docking at the cell surface, and how these go awry in Meckel-Gruber and Joubert syndromes. I am a member of the Cell Biology research group.

Research interests

Eukaryotic cilia and flagella are remarkably conserved, both at the structural and functional levels, from evolutionarily ancient unicellular eukaryotes to man and are adapted to carry out diverse roles. Almost every cell in the human body can form a cilium or flagellum, either motile or non-motile. Motile cilia move fluids past epithelial cell layers in multicellular organisms; however, non-motile primary cilia are the most common type of cilia in the body. The roles of primary cilia were unclear but the recent identification of many inherited disorders involving aberrant ciliary function, termed “ciliopathies”, has changed this and primary cilia are now known as sensory organelles, acting both as chemo- or mechanosensors and transducers of signals that regulate key developmental signalling pathways. My lab focuses on the severe ciliopathy Meckel Gruber syndrome. We use a combination of patient-derived cell lines, post-genomic technologies, classical cell biology and genetics to give insight into the molecular cell biology of the disease. We are currently studying the roles that two proteins, TMEM67 and TMEM216, play in organisation of the actin and microtubule cytoskeletons during cell migration.

Research projects

Current research falls into the following overlapping projects:

  • the mechanism of centrosome migration to the apical membrane during ciliogenesis of primary cilia
  • the molecular cell biology of Meckel-Gruber and Joubert syndromes
  • the role of MKS proteins in non-ciliated cells
  • the role of cilia in setting up the left-right axis in invertebrates
