My main research interest is to examine the mechanisms that maintain social monogamy in mammals and the role that sexual selection may have had in the evolution of this unusual mating system. I am also motivated to study living primates as an approach to understanding the evolution of human behavior. I am particularly interested in male-female relationships, pair bonding and paternal care in humans and non-human primates.
