Sexual selection in freshwater fishes: I use freshwater fishes as model systems to study sexual selection. Projects focus on genetic compatibility, sexual conflict, sperm competition and post-mating female choice. Sexual selection in marine broadcast spawners: This component of my work focuses on sperm competition, genetic compatibility and the benefits of polyandry in marine invertebrates. The work investigates compatibility at the gamete level and the interacting effects of male and female genotypes on fertilization success and offspring fitness.
