The goal of the Population Genomics Group (PGG) is to understand the evolutionary dynamics of genomes at population level using computational approaches, and to bridge evolutionary history and genomic medicine. Currently, PGG is focusing on analysis of genetic structure, inference of human genetic history, detection of natural selection, mapping genes underlying complex diseases in human populations, and identifying the differentially expressed genes among populations. A new focus is to study allele-allele interaction and gene-gene interaction in recent admixture populations.
