Research Interests

My research interests include the ecology, conservation and management of waterfowl and wetlands. My students and I have studied numerous species of ducks and geese (mallards, wood ducks, northern pintail, Barrow’s and common goldeneye, Steller’s eider, cackling geese, white-fronted geese, trumpeter swans, Orinoco geese and black-headed ducks) at study sites ranging from Alaska to Argentina. Other students working with PRBO Conservation Science are using long-term data sets to understand the population dynamics and response to habitat perturbation of several groups of terrestrial landbirds and seabirds. My current research focuses on evaluating management and conservation of moist-soil wetland habitats, determining the factors limiting population size and production of breeding waterfowl (mallards and wood ducks) in California, and linking population and ecological theory to wildlife management and conservation. We use a combination of experimental and observational field studies, molecular genetic techniques in the lab, and population and agent-based modeling approaches in our research.
