Her long term research examines the ecology and evolution of migratory birds. Her current research explores interactions between migration strategies and life history traits in arctic-nesting birds. Much of this research involves quantifying the costs and benefits of migration by estimating adult survival, reproductive success, and ecological conditions for birds breeding at various latitudes. She is also investigating how potential reproductive benefits of migration may be threatened by climate change by combining an ecosystem approach with physiological investigations to study the growth and survival of offspring in a changing arctic climate. This research will provide valuable insight into the potential effects of climate change on arctic-nesting birds.
