I study long-term viability and extinction risk in endangered species. My research is focused on how environmental factors interact with inbreeding depression to contribute to a decline in fertility in the endangered black-footed ferret.
I am interested in monogamous mating systems, and the outcome of brain, behavior, and physiology due to infertility in birds. I also explore sexual selection and blood parasitism with regard to avian behavior.
I am an ornithologist interested in how the decisions of individual animals scale up to evolutionary processes. My research spans across many aspects of avian natural history, from interspecific competition, to signal evolution and movement ecology.
