I am an integrative evolutionary ecologist with a particular interest in the evolution of animal communication. I try to understand basic processes in ecology and evolutionary biology through a combination of field studies, comparative methods, and theoretical modeling.

Female spiders fight by different rules (an example of Grafen's 'desperado effect' in the wild)
Climatic variability predicts the elaboration of song displays in mockingbirds. 2009. Current Biology.
Mockingbirds exposed to more variable and unpredictable climates have more elaborate song displays. When the going gets tough, the tough sing better!!
Bird song research
An important component of my work is a series of field studies on song use and song learning in mockingbirds.

I am also interested in developing new theory for the evolution of communication. Follow this link to learn more about my approach to modeling this process.
