Research Interests

My research interests range broadly in evolutionary and behavioral ecology. Special interests include life history theory, mating system theory, and optimal foraging theory. I emphasize experimental approaches to the study of adaptation, particularly with species that display geographical variation in the characteristics of interest. Current research uses birds as study systems, but taxonomic interests include most vertebrates and insects. Current projects include 1) the evolution of sexual dichromatism and cavity-nesting in the Hawaii Akepa, 2) the evolution of reproductive rate and permanent monogamy in tropical House Wrens in lowland central Panama, and 3) evolution of introduced birds in Hawai`i. I am closely associated with researchers in the Hawaiian Evolutionary Biology Program in attempts to use both native and introduced species in Hawai`i as model systems for understanding evolutionary processes.
