I am broadly interested in reproductive biology, sexual selection and mating system evolution. My main research aim is to understand the adaptive significance of female promiscuity and the evolution of male mating strategies in polyandrous mating systems using invertebrates as model organisms, particularly spiders and crickets. Together with experimental laboratory trials through which I study male reproductive behavior, sperm traits and resulting fitness in response to changing selective pressures (intra-sexual competition) I also conduct field studies to assess the ecological factors that may ultimately constrain encounter rates among potential mating partners and among competitors and affect mating strategies in natural populations. I apply molecular methods to estimate natural mating rates and paternity patterns, both in the wild and in laboratory experiments, to understand the strength of post-mating selection in shaping reproductive traits and its interaction with pre-mating selection, ecology and life history evolution.
