Personal Statement

Dr. Shaffer's research program involves the application of statistical and bioinformatics approaches to understand the genetic contributors to common complex human diseases. In particular, Dr. Shaffer is interested in heritability, linkage analysis, genetic association, epigenetics, and gene-by-environment interactions. His current research projects include studies of oral health, craniofacial phenotypes, and recovery from brain injury.
