Research Interests

My research interests include avian vocalizations, the distribution and behavior of amphibians, and conservation. I study the relationships between the social system and the structure, pattern, and function of female Red-winged Blackbird vocalizations, and how female redwing vocalizations influence the fitness of males and female redwings.

I also study the distribution of a diploid/tetraploid complex of tree frogs that occurs together across much of the eastern and central U.S. My main interests are the historic processes that produced the current distribution, and how natural selection maintains the separation between the two species (Hyla chrysoscelis and H. versicolor).

I am very concerned about declining wildlife populations, and I work locally and internationally to promote conservation efforts, particularly in developing countries.
