- Research Interests -
- Our laboratory is interested in the mechanisms controlling tissue patterning during mammalian embryonic development. Using the mouse as a model, we exploit a combination of reverse and forward genetic approaches to investigate signaling pathways that function in cell fate specification in different contexts. Our work has primarily focused on identification of novel regulators of the Hedgehog signaling pathway acting within the developing central nervous system. In addition, we have recently begun to examine the regulation of Nodal signaling in the control of patterning along the left-right axis of the mouse embryo. Building upon our genetic analyses, we are working to elucidate the specific functions of these novel regulatory factors at the cellular and biochemical levels.
