My group works on the interactions between human genetic and cultural evolutionary systems, integrating methods and data from population genetics, anthropology, archaeology, historical linguistics and quantitative history. Gene-culture coevolution is the comprehensive study of human evolutionary history, drawing from a range of disciplines to infer the uniquely human processes underlying the distribution of modern or ancient genetic variation. We develop simulation and statistical inference methods, including geographic and palaeoenvironmental modeling, to create a unified framework for human demographic inference.
