Norah Dunbar studies credibility and deception in a variety of contexts. In particular, she studies how dominance, nonverbal synchrony, and other nonverbal behaviors affect the impressions we make in our interpersonal relationships. She has examined interpersonal power as it relates to credibility and persuasion and has pioneered the methods of measuring nonverbal behaviors.
Dr. Dunbar is a Professor of Communication at UCSB and a Fellow of the International Communication Association. She teaches courses in nonverbal and interpersonal communication, communication theory, and deception detection. She is also Affiliate Faculty in the Center for Information, Technology & Society; Center for Responsible Machine Learning; the Center for Digital Games Research; and the Quantitative Methods in the Social Sciences program. She has received over $18 Million in research funding from agencies such as the Intelligence Advanced Research Projects Activity, the National Science Foundation, the Department of Defense, and the Center for Identification Technology Research. She has published over 100 journal articles, book chapters, and encyclopedia articles and has presented over 120 papers at National and International conferences. Her research has appeared in top journals in her discipline including Communication Research, Communication Monographs, and Journal of Computer-Mediated Communication as well as interdisciplinary journals such as Journal of Management Information Systems and Computers in Human Behavior. She has served on the editorial board of over a dozen disciplinary journals and as the Chair of the Nonverbal Division of the National Communication Association in 2014-2016.
