I am a behavioural ecologist and my main research interests are the evolution of sociality and its cognitive implications. In my PhD project I focus on family and parent-offspring relations in humans and I investigate how parents affect the behaviours and fitness of offspring. I apply population models to genealogical, life-history and environmental data of various human societies to examine socioecological patterns of: marriage between cousins, celibacy and inequalities in inheritance and parental investment. My goal is to understand whether these behaviours are instances of "parental manipulation", an evolutionary phenomenon common to many taxa and particularly widespread in humans that enhances parents' fitness at the expenses of (some) offspring's fitness, or they are different adaptive strategies. In both cases, I examine the selective forces that have driven the evolution of these behaviours and I use comparative analysis to see similarities and differences with other species.
