What are the oral health determinants of quality of life? How can improved oral health positively influence educational success and psychosocial functioning? My research lies at the intersection of dentistry, public health, and education. Specifically, I study the effects of school-based caries prevention and the impact of craniofacial surgery on child development in children with cleft lip/palate.

In addition to my academic appointments, I am also the Director of the MS Program in Clinical Research and Director of the Biostatistics Core.
