Our group's research is focused on the understanding of the current genomic diversity in human populations in order to establish the mechanisms, causes and consequences of this genetic variation. Concerning population processes, the research of our group has focused on the analysis of uniparental markers (Y-chromosome and mitochondrial DNA) as well as autosomal markers to answer several questions about the origins of human populations. Within this framework we have addressed questions about the population history of Central African groups, the peopling of the Americas, or the diversity within North African populations. Concerning genomic processes, our research has focused on the analysis of the diversity of genes involved in complex diseases in order to describe the standard diversity in healthy individuals and to unravel its implications in disease, such as psychiatric and immunological disorders.
