I am broadly interested in animal behavior, neuroethology and evolution. My research focuses on social insects, which have been pivotal in understanding communication, social behavior, sensory systems, learning and memory and behavioral ecology. They can be approached at many levels of biological organization, from individual organisms to a functioning whole colony. My research training is broad, as I have studied social insect colonies from the individual and group levels, but my questions center around understanding adaptations of social behavior. I have investigated questions ranging from neuroanatomy and behavior, chemical cues involved in kin recognition, mechanisms of task specialization in ant colonies, population and colony level genetics of honey bees and mechanisms of genetic caste determination. |
