Research Interests

Community ecology and biological diversity of tropical social insects, especially of army ants (Formicidae: Ecitoninae)

  • Behavior and ecology of bird-army ant interactions, especially in montane forests
  • Social behavior, especially of eusocial Hymenoptera: Behavioral, genetic and physiological regulation of division of labor in wasps (Vespidae) and bees (Apidae)
  • Brain/behavior relationships and the evolution of brain structure in social insects
  • Network models of social group organization
