Behavioural ecology - the study of how an animal's ecology and behaviour influence its ability to pass on its genes, either through its own offspring or via close relatives. More specifically I am interested in family interactions in birds with particular emphasis on mate choice and parental care. Birds provide excellent systems for studying these interactions because individuals are relatively easy to observe and the different components of the costs and benefits can be quantified. My earlier work focused mostly on sexual conflict between parents by trying to understand how parentage and parental care interact in polygynous and polyandrous matings. More recently, I have become interested in other within-family interactions, such as parent-offspring conflict and sibling competition.
