He earned is Bachelor’s degree from Swarthmore College and his PhD from Colorado State University. His postdoctoral studies were completed at the California Institute of Technology. His interests include the neurobiology of vocal production and the perception on songbirds. He has recently begun study in neural circuitry underlying mate preference and copulatory display in the brown-headed cowbird. Marc finds it interesting that birds seem to use the same circuits in the brain for singing as they do to control sex.
