How are Notch signals decoded by developing tissues? 

To make and organize tissues, cells need to communicate with each other and to correctly decipher the information they receive –mistakes are at the root of many inherited diseases and cancers. Our research has a focus on the Notch pathway, which provides key information during tissue development and maintenance.  A critical end-result from Notch activity is that genes are turned on; our goal has been to discover how this occurs accurately in developing animals. We have recently developed several cutting-edge strategies to visualize key events in real time within living embryos and tissues. PhD projects would build on these tools to address key questions about how Notch signals are decoded by cells in different developmental processes, such as neurogenesis.
