Research Interests: As a behavioral ecologist I am interested in evolutionary and ecological processes that generate the broad diversity of animal behavior. My research involves the evolution of social behavior with a specific focus on the evolution of parental care and communal breeding. Many animals decrease the costs of parental care by raising their offspring with other parents in a communal group. However individual parents within these groups often experience large asymmetries in the number of offspring that they produce and the amount of care that they provide. My work attempts to understand how these asymmetries can be maintained within social groups and how group members act to resolve these conflicts over reproduction and parental care. My general approach is 1) to develop mathematical models that are applicable to a broad range of social animals and 2) to test the predictions of these (and other) models using laboratory and field experiments on social animals.
