研究领域

My lab studies sexual signaling behavior in crickets, and how that signaling behavior affects male mating success (sexual selection), likelihood of being attacked by a killer parasitoid fly (natural selection), and how evolutionary changes in male songs and female preferences for songs affect reproductive isolation and speciation.
