Research Interests

My research focuses on the ecology, behavior, and evolution of birds. Specifically, I am interested in the ecological and evolutionary consequences of interactions between organisms. These interactions may be between mothers and their offspring (i.e., maternal effects), how organisms respond to species introductions or among similar species in competition for limited resources.
