Nazbanou Nozari, M.D., Ph.D.
Assistant Professor of Neurology
Research Interests: Language production, Executive control, Aphasia
Dr. Nazbanou Nozari is an assistant professor of neurology at the Johns Hopkins University School of Medicine. She is also a member of the Department of Cognitive Science at the Krieger School of Arts and Sciences at Johns Hopkins University.
Her research focuses on understanding the cognitive and neural architecture of the language production system and how it interacts with other cognitive systems, especially the executive control system. Her recent work has expanded this focus to language learning, as well as re-learning of the lost language after brain damage.
Dr. Nozari received her M.D. at Tehran University of Medical Sciences in Tehran, Iran. She completed an MA in cognitive psychology from the University of Illinois at Urbana-Champaign in Champaign, Illinois. She earned her PhD in cognitive psychology, from the University of Illinois at Urbana-Champaign in Champaign, Illinois.
She completed a post-doctoral fellowship in cognitive neuropsychology at the Moss Rehabilitation Research Institute as well as a postdoctoral fellowship in cognitive neuroscience at the University of Pennsylvania. Prior to joining Johns Hopkins, Dr. Nozari was a post-doctoral researcher and undergraduate mentor at the University of Pennsylvania.
In 2016 she was elected to the Academy of Aphasia Membership Board as well as the editorial board of Frontiers in Psychology journal (Cognition section). Her work has been recognized most recently with the American Psychological Association’s New Investigator Award, as well as by being selected for the Emerging Women Leadership Program at Johns Hopkins University.

Research & Publications
My research focuses on understanding the cognitive and neural architecture of the language production system and how it interacts with other cognitive systems, especially the executive control system. Together with my students and my collaborators, we have several lines of research, studying the role of executive control in lexical retrieval and grammatical encoding in children, younger and older adults, bilinguals, and individuals with aphasia, with the overarching goal of understanding how the language production system is monitored and regulated. My recent work has expanded this focus to language learning, as well as re-learning of the lost language after brain damage.
