Research Interests:

I’m a broadly trained naturalist with interests in ecology, natural history, biodiversity, and conservation biology. My research deals with avian ecology and conservation. I’ve conducted ornithological fieldwork in the United States, Peru, and Japan. My primary research interest is habitat use by birds. Studying habitat use is important for understanding wildlife ecology and for the management and conservation of wildlife, including birds. A secondary research interest of mine is the effects of human habitat modification on bird communities.
