Research centres on understanding the process of speciation in heliconiine and ithomiine butterflies. Both groups of butterflies are found in the neotropics and are noted for the diversity of wing colour patterns found within species, as well as also for mimetic convergence of colour patterns between species (Müllarian mimicry).

Making use of the Heliconius melpomene reference genome, the current focus involves using high-throughput sequencing approaches to understand the speciation process at the scale of the genome. In particular we are investigating genome-wide patterns of divergence, adaptive introgression, and quantifying the amount of genomic exchange between species.
