We study adaptation and speciation, with a special focus on the genetic basis of wing pattern mimicry in butterflies. Other topics of study in the lab include mate preference evolution in butterflies, monarch butterfly migration, and poison dart frog color patterning. Our work is highly integrative, spanning genomics, population genetics, molecular and developmental biology, animal behavior, and field work.
