Dr. Zahra Jafari possesses a diverse academic background and engages in interdisciplinary research. Prior to her affiliation with Dalhousie University, she held a Postdoctoral Fellowship (PDF) position in the Neuroscience Department at the Canadian Centre for Behavioral Neuroscience (CCBN), University of Lethbridge. This position significantly contributed to the advancement of her research in human and animal neuroscience. Further, she has experience working for the Canadian Agency for Drugs and Technologies in Health (CADTH) as a clinical research officer, which provides Canada's healthcare decision-makers with objective evidence to help them make informed decisions regarding the optimal use of drugs, medical devices, diagnostics, and procedures in the healthcare system. Dr. Jafari's research pursuits are focused on various areas, including healthy aging, modifiable risk factors for dementia, cognitive fatigue, tinnitus, auditory aging, multilingualism, music perception/interventions, neuroimaging, and evidence-based research.
Dr. Jafari accepts the supervision of graduate students in the PhD in Health program (https://www.dal.ca/faculty/health/programs/phd-in-health.html), the Interdisciplinary PhD program (https://www.dal.ca/academics/graduate_programs/interdisciplinary-phd.html), and Master’s Theses in Communication Sciences and Disorders (https://www.dal.ca/faculty/health/scsd/research/student-research.html).
