Natural biological systems are exceptionally diverse in terms of species richness, phenotypic form and function, and ecological interactions. Our research seeks to explain the origin and maintenance of this diversity across multiple levels of organization, from individual nucleotides to entire communities. As a tool to understanding the dynamics of biological diversity, much of our work focuses on adaptive phenotypic diversification and speciation in tropical butterflies, such as the genus Heliconius.

The Heliconius Genome paper was published in Nature.

Please see my new Perspective in PLoS Genetics, discussing recent evidence for adaptive introgression of mimicry in Heliconius.

Our new review paper on pigmentation genetics was just published in Pigment Cell & Melanoma Research.
