Research interests

My research interest focuses on evolution and function of animal behaviour. I have ongoing projects in three different areas:

  • Sexual selection and sexual conflicts in poeciliids fish
    In many species the two sexes have divergent interests in reproduction. Conflict over mating frequency is prominent in poeciliids as females store sperm and need a few copulation while males are very ardent and attempt to mate with all females they encounter. We study the consequences of male sexual harassment and the strategies used by females to minimize the costs of sexual conflict

  • The evolution of cerebral lateralisation in vertebrates
    The presence of cerebral lateralization is now firmly established in almost all vertebrate classes. We are presently investigating the selective advantages of functional brain asymmetries and the mechanisms explaining the maintenance of individual variation in these traits

  • Cognitive mechanisms in fish
    We study visual perception, spatial orientation and numerical abilities in teleost fish. We are especially interested in understanding how ecology and phylogeny interact to produce similarity and variation in cognitive mechanisms across vertebrates
