<i>Research interests</i>
I study the molecular evolution of ants using genomic tools. As part of the Keller group I joined the analysis of the newly sequenced genome of the red imported fire ant Solenopsis invicta. This species is a unique model for the evolution of sociality because the genetic basis for a Mendelian trait affecting social behavior is known to be a non-recombining, Y-like "social chromosome" (Wang et al. 2013). The recent evolution of this system must have involved many micro- and macro-mutations that alter social organization, which are expected to be under selection in social animals. I apply comparative genomics and population genomics to study the evolution of this social chromosome and the specific genes that underlie the various biological functions responsible for this social polymorphism, especially chemical communication. In the past I have been working on algorithms for phylogeny and sequence alignment, and on applied research of co-evolving genes and of nucleases for use in gene therapy (see my old homepage)
