Benita Hosseini


Scientist, Li Ka Shing Knowledge Institute


Dr. Banafshe (Benita) Hosseini is a Research Scientist at the Upstream Lab, MAP/Centre for Urban Health Solutions, Li Ka Shing Knowledge Institute. Dr. Hosseini received her PhD in Nutrition Science from the University of Newcastle, Australia. Prior to joining the Upstream lab, she completed her Postdoctoral Fellowship at the University of Montreal, where she contributed to several projects addressing the impact of dietary intervention on respiratory illnesses in children and adults. Her research focuses on nutritional approaches to managing respiratory diseases, this includes exploring the association between food insecurity, malnutrition and severity of acute respiratory infections and how dietary intervention can enhance immune responses to respiratory infections. She is also interested in investigating therapies for manipulating the Gut-Lung axis in asthma and chronic obstructive pulmonary disease. Currently, Dr. Hosseini is mainly working within the CanTreatCOVID research group. She has been directly involved in the rapid roll-out of the CanTreatCOVID study, which is a nation-wide adaptive platform trial designed to identify effective and affordable medications for COVID-19 so they can be made readily available in community settings.
