I am interested in the evolution of sexual dimorphism. Males and females vary for a variety of morphological, behavioral, and developmental traits. How do such differences emerge? Because males and females share a common underlying genome, selection in one sex can produce a correlated response in the opposite sex. Until this genetic correlation abates, sexual dimorphism will evolve only very slowly. An important question in evolutionary biology thus remains: what are the mechanisms that can decrease the intersexual genetic correlation?
I use experimental, genomic, and theoretical approaches to study how males and females can evolve differences where before there were none. I have shown that condition can modulate the amount of male-to-female differences in gene expression in Drosophila melanogaster. I am now working on the implications of gene duplication for the sex-specific optimization of transcription. My future plans include more broadly exploring the consequences of sex-linkage for the evolution of dimorphism.
