Graham Coop is a population geneticist who has worked on a remarkably broad range of theoretical and empirical questions—contributing to our understanding of local adaptation, human evolution, and the effects of linked selection. In addition to his own work, an impressive group of postdocs and students have trained in his lab, where he mainly just makes the tea.
Graham is a Professor in the Department of Evolution and Ecology at UC Davis; you can read more here.
Spatial patterns in genetic variation reflect the movements of the ancestors of the sample. In this talk, I will explain how to use genome-wide genealogies and the locations of contemporary samples to infer dispersal rates and the locations of their genetic ancestors. I'll show how this method can be used to reconstruct range expansions of species using data from Arabidopsis thaliana. This is a joint project with Matt Osmond.
