Our research focuses on the development of statistical methods for uncovering the genetic basis of human disease, and on the population genetics underlying these methods.
EIGENSOFT uses PCA to correct for population stratification in medical association studies (EIGENSTRAT, Price et al. 2006) and to detect and analyze population structure (SMARTPCA, Patterson et al. 2006).
"HAPMIX (Price et al. 2009) uses genotyping data from SNP arrays to infer chromosomal segments of distinct continental ancestry in admixed populations, and can be downloaded."
