Education and/or Training

Ph.D.	2008	University of Alaska Fairbanks, Fairbanks, AK	Biology
M.S.	1996	University of Idaho, Moscow, ID	Zoology
B.S.	1990	Lewis and Clark College	Biology

Areas of Specialization and/or Research Interests

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.
