Areas of Specialization and/or Research Interests

Since 1990, I have worked at the Alaska Science Center (ASC) as a wildlife biologist and geneticist on a variety of bird projects focusing on species of shorebird, waterfowl, and landbird. Beginning in 1994, I also worked in the USGS Molecular Ecology Laboratory in order to add a genetics component to our study of wildlife populations and avian influenza viruses. Since 2012, I have been Chief of the Wetlands and Terrestrial Ecosystems Office, overseeing broad science initiatives on wildlife response to climate change, avian disease, environmental health, and genomic investigations in the state of Alaska and adjacent regions that share wildlife questions and resources with Alaska.
