Professor Floyd's research focuses on the communication of affection in personal relationships, and on the interplay between communication, physiology and health. He has studied affectionate communication in a host of family relationships, as well as between romantic partners, friends, and new acquaintances. His work in the Communication Sciences Laboratory demonstrates how affectionate behavior can alter stress hormones, lower blood glucose, reduce lipids, and improve immune system parameters. His most recent project, funded by the National Institutes of Health, investigated the role of the peptide hormone oxytocin in the stress-alleviating effects of affectionate communication.
Professor Floyd is past chair of the family communication division of the National Communication Association and immediate past editor of the Journal of Family Communication.
