Social insects are exemplars of biological complexity and, together with humans, are among the most evolutionarily successful and ecologically dominant animals on earth. We study the behavioral mechanisms, ecology, and evolution of social behavior in insects, with an emphasis on collective intelligence, division of labor and their influence on brain evolution. Darwin was excited by the ant brain’s capability of “extraordinary mental activity with an extremely small absolute mass of nervous matter.” We feel the same way. By exploring the neuroanatomy and neurochemistry of social behavior using immunohistochemistry, confocal microscopy, high-performance liquid chromatography and pharmacological interventions to examine the regulation of task performance and behavioral development, we seek to understand the neurobiology of social structure in light of ecology and evolution. Our integrative studies connect sociobiology, neurobiology, physiology, gerontology, and ecology to understand the selective forces associated with social brain evolution in ants, and how the brain meets the demands of processing complex information at the level of the individual and society as a whole. Research centers on the evolution and neural architecture of the social brain, measuring its metabolic rate using microrespirometry, and determining social metabolic scaling. We are also interested in the genomics of social brain evolution.
