Research Interests

Biological families create opportunities for cooperative interactions but are also fraught with conflict. My research seeks to understand how cooperation and conflict among family members affect evolutionary change. I am especially interested in whether family life can be a catalyst for the formation of new species, how traits in parents and offspring coevolve, and whether conflict between family members can drive the evolution of complex adaptations. As a broadly trained evolutionary ecologist, I combine techniques and concepts from behavioral ecology, life-history theory, molecular biology, and experimental evolution to test evolutionary theory. My current research focuses on beetles in the genus Nicrophorus, however I also have strong interests in the ecology and evolution of placental fish.
