I am interested in how behaviour and communication evolves within animal social groups (particularly bird families) when there are conflicting evolutionary interests among the parties (e.g. parents and offspring or nestmates, including brood parasites and their hosts).

In particular, I have studied the evolution of begging signals in nestling passerines and how this communicative system can be exploited by parasitic cuckoos.

I have further explored how cooperation and conflict are expressed in other, non-passerine species where begging signals play a secondary role in parent-offspring interactions, such as storks. In combination with observational and experimental studies, I use comparative methods to get a comprehensive picture of how a life-history perspective can integrate the enormous diversity in behavioural and physiological traits by which cooperation and conflict are expressed within avian families.
