Research Interests

For details, visit my website: The Barbosa Lab

I am a behavioral ecologist interested primarily in sexual selection. I study mating behavior employing insects as model species, both in the field and the laboratory. My current research is on katydids and moths, but I have also worked with flies, beetles and treehoppers.

I am fascinated by the degrees of elaboration and variation in animal mating traits, including courtship displays, mating songs, elaborate genitalia and nuptial gifts (items offered to a mate during courtship or copulation). In most species, males compete for mates, while females have mate preferences, choosing their mates based on certain male traits. Female preferences can therefore exert strong selective pressure on males, playing a major role in the elaboration and diversification of mating traits, and potentially generating population divergence and speciation. My research focuses on the evolution of traits used to attract mates, the costs and benefits of reproductive investments, and the mechanisms and functions of mating preferences.
