Profile Introduction

Molecular mechanisms underlying craniofacial and forebrain development.

Research Interests

Our research interests focus on the molecular and cellular mechanisms that direct the development of the craniofacial skeleton and forebrain. Particular emphasis is put on the analysis of the molecular program underlying the differentiation of cranial neural crest cells. Additional projects investigate the cues that guide the migration, differentiation, and connectivity of cortical neurons.  In our studies, we take advantage of mouse lines with striking craniofacial or neurodevelopmental defects caused by mutations in specific genes. Our laboratory is seeking highly motivated graduate students who would like to pursue a project in prenatal developmental biology. Undergraduates who are interested in developmental biology and are able to commit for at least two semesters are also encouraged to apply for research internships.
