Since 1990, I have worked at the Alaska Science Center (ASC-BSO) as a wildlife biologist on a variety of bird projects focusing on species of shorebird, waterfowl, and landbird. Since 1994, I have worked in the ASC-BSO Molecular Ecology Laboratory in order to add a genetics component to our study of wild birds. Currently, we use nuclear and mitochondrial DNA markers to: investigate differences among breeding and wintering populations of birds; examine behaviors and movements of birds; and apply results from these studies to the monitoring of wild bird species.
