My research focuses on how natural selection and sexual selection interact. Specifically, I am interested in how natural selection on traits that are closely related to fitness (life history traits) affects the strength of sexual selection and visa versa. To explore how these two kinds of selection interact, I use both lab and field experiments along with theory and computer simulations.
I am currently studying how nutritional ecology and social interactions affect both insect movement and mating behavior. I am also currently studying whether sexual selection can explain pervasive patterns of sex differences in rates of recombination during meiosis.For more detailed and up to date information, see my lab website.
