I study the evolution of social behavior and social organization in ants and other social insects using evolutionary genomic approaches, including both population genomics and phylogenomics. Various research projects in the lab involve studies of natural populations of ants in the field, collection of samples, behavioral experiments in the lab, genomic sequencing, and a wide range of computational analyses. We developped genomic infrastructures for the desert ant Cataglyphis niger as our focal study organism, and recently we discovered a supergene in this species (a.k.a. “social chromosome”).
