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 am interested in the comparative effectiveness of school-based caries prevention and the impact of craniofacial surgery on child development in children with cleft lip/palate.

I am an Assistant Professor at the New York University College of Dentistry and the College of Global Public Health. I am also the Director of the MS Program in Clinical Research and Director of the Biostatistics Core.
