Research Interests
Our group focuses on the developmental mechanisms controlling cell fate specification during development. The primary goal is to define gene regulatory networks that initiate and guide patterning of the primary tissue layers, ectoderm, endoderm and mesoderm, in early embryos. The structure of these regulatory circuits involves the interplay between transcription factor activities and signaling pathways. Of particular interest are the networks underlying the development of neural and non-neural ectoderm in the anterior regions of embryos, which give rise to the mouth and primitive nerve net in basal deuterostomes and to tissues of the head in their evolutionary descendants, the vertebrates.
