Fields of study
Sexual selection and speciation
Research interests
I am interested in sexual selection and the divergence of reproductive characters among populations. Specifically, I am investigating whether variation in male secondary sexual traits in crickets of the genus Amphiacusta can be explained by a null model of genetic drift. My work focuses on measuring interpopulation variation in male genitalia and courtship song and comparing the variation in these traits with expectations of phenotypic variance generated by a null model of genetic drift using SNPs. If the observed variance does not differ significantly from that expected under a neutral model, we cannot reject the null hypothesis that divergence is the result of genetic drift. Alternatively, if the level of variation observed is significantly greater than the neutral expectation, we can conclude that diversifying selection is responsible for reproductive character divergence in this genus.
