Core Research Area

The University of Iowa College of Dentistry is a worldwide leader in the genetics of craniofacial and dental development.

Craniofacial anomalies are among the most common forms of birth defects. The goal of this research group is to identify both genetic and environmental causes for facial birth defects, with a primary focus on orofacial clefting, including cleft lip and cleft palate. Our center builds upon a 40-year history of clinical and research studies on craniofacial anomalies at The University of Iowa and continues the tradition established over the past decade of interdisciplinary and inter-institutional research. The research includes not only a broad-based internal constituency but collaborative projects and interactions with colleagues in the United States and overseas. These projects offer access to novel populations and innovative techniques. A variety of approaches are utilized, including genetic and epidemiologic studies of human populations, and the development of animal models that are characterized through molecular biological and biochemical analyses, in addition to a variety of sophisticated imaging techniques.
