Description of Current Research and/or Professional Activities:

The lab research focuses on social evolution and genetics. We study bees to understand the genetic underpinnings and ecological constraints selecting for social behavior. This research includes:

  • Field and lab experiments in New England and Australia to understand the behavior and ecology of native bees.
  • Genomics to understand relatedness and gene expression of individuals in social groups.
  • Molecular phylogeny to understand bee biodiversity, historical biogeography, as well as the age and origin of sociality.
