I’m broadly interested in how new species evolve, and the evolutionary implications of ongoing hybridization between newly formed species. I completed my PhD at the Department of Animal Ecology, Uppsala University, and my thesis research focused on a hybrid zone between collared and pied flycatchers in Sweden. This work addressed a variety of topics ranging from the degree of niche overlap between the two species and the direct and indirect fitness consequences of hybridization, to genetic linkage between traits underlying assortative mating. Currently, I’m further exploring the genetic architecture of sexually selected traits important in behavioral isolation between closely related species of Hawai’ian crickets in the genus Laupala. In collaboration with Kerry Shaw, I am investigating the degree of physical linkage between genes underlying variation in male song and female preferences for these songs. By understanding how the male and female components of sexual communication coevolve and diversify, we aim to uncover the reasons for the rapid and impressive species radiations that typify this and other taxa.
