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, epidemiology, and education. I am interested in the impact of school-based caries prevention on oral health and student achievement, and the effects of craniofacial surgery on the quality of life of children with cleft.

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