Lepidoptera

I am interested in gaining a better understanding of the evolutionary forces and the underlying genetic changes that drive adaptation and speciation in natural populations. Research in my lab uses a combination of comparative genomics, phylogenetics, population genetics, laboratory crosses, field and behavioral experiments to study adaptation and speciation in Drosophila and Heliconius butterflies.

Current Research Projects
Genetic basis of adaptive color patterns in Heliconius butterflies

Evolutionary history the adaptive radiation of color patterns in Heliconius

The role of natural selection and sexual selection in maintaining species and racial boundaries in Heliconius

Sequencing of the Heliconius genome and comparative genomics on Lepidoptera
