Research Interests

We investigate  cellular and molecular mechanisms underlying the development of the nervous and skeletal systems during embryonic development. Specifically, we seek to uncover the gene regulatory networks responsible for lineage segregation and specification of embryonic epithelia, such as the premigratory neural crest and the somite. In addition, we investigate cell migration and patterning of nascent structures such as ganglia and muscles and aim at understanding the relationship between specification and the control of subsequent cellular migrations.​
