Expertise / Specialty:Avian Ecology and Conservation; Demographic Modeling; Conservation Genetics

Research Interests:My research focuses on understanding factors that affect population dynamics – why populations increase or decline over time – and through an understanding of the “why” populations change in size provide natural resource managers information on “how” to maintain healthy populations. My research has focused mainly on birds, mostly endangered species, using field research, modeling, and genetic research to understand population dynamics and identify possible conservation actions to help imperiled populations. My work in Hawaii is focused on the native Hawaiian forest birds.
