Description of Research Expertise:
Cell Polarity, Embryonic Morphogenesis, Developmental Genetics
Proper control of cell polarity is essential for all cells. Healthy mammalian epithelial cells maintain apical basal polarity, while cancerous epithelial cells exhibit defects in the orientation of their division axis. Our studies using the nematode C. elegans combine genetic, molecular and biochemical approaches to investigate how specific proteins are used to regulate cell divisions and cell migrations at key points in development.
Current projects in the lab focus on the role of the GEX complex, a regulator of the actin cytoskeleton, in polarized events during development including epidermal cell migration, epithelial cell polarization and regulated nuclear movements.
