My research interests lie in understanding the development of teeth and orthodontic tooth movement. This involves a wide spectrum of questions such as:
How do teeth form? Are there other functions of teeth besides mastication, particularly in systemic health? Can teeth be used as diagnostic markers of systemic disease? How do teeth move within the alveolar bone during eruption and orthodontic treatment? Can we induce human teeth to grow continuously like rodent incisors? The answers to such questions may lead to improvements in the prevention, diagnosis, and/or treatment of dental-related problems in the clinic.
We have generated several mouse models with fascinating tooth phenotypes and are currently uncovering the molecular mechanisms responsible for the phenotypes. We also have numerous mouse studies underway looking at the roles of soft and hard food diets on craniofacial morphology, the effects of inferior alveolar nerve block on third molar agenesis, and gene expression profiling during orthodontic tooth movement.
