What would you do if you could travel back in time? In the field of human population genomics, that is the question we are now asking ourselves, since during the past decade genomic sequencing technology has suddenly made it possible to directly trace evolution—defined as genetic change through time—using historical observations. This field is called ancient DNA, and it is starting to bring about a new era of genomics that promises to revolutionize our view of many species, and as we are usually prone to, we have started with ourselves.

I am a postdoctoral research fellow in David Reich's lab at the Department of Genetics of Harvard Medical School and the Broad Institute of MIT and Harvard. In my research I use large-scale DNA information to learn about the human past. I develop statistical methods for reconstructing population history and bioinformatic methods for ancient genomics with the goal of addressing outstanding questions in archaeology, anthropology and natural history. Examples include population dynamics during prehistoric transitions to agriculture, the peopling of the Americas, and interactions between early modern humans and archaic populations.
