Manali Mukherjee, MSc, PhD

Dr. Mukherjee is an Assistant Professor in the Division of Respirology, Department of Medicine, and a translational scientist affiliated with the Research Institute of St. Joe's, Hamilton. Her expertise lies in the arena of developing/validating airway biomarkers, mechanisms of airway inflammation, and response to biologic therapies. She has identified the presence of localized autoimmune responses in the airways of patients with complex airways disease, and determined their pathogenic role in driving disease severity, particularly in asthma, and eosinophilic granulomatosis with polyangiitis (a systemic autoimmune disease with pulmonary complications).Dr. Mukherjee’s research program thus focusses on “Lung autoimmunity and biomarkers”. She is the current recipient of the Emerging Researcher Award in Allergic Asthma awarded conjointly by the Canadian Institutes of Health Research (CIHR) and the Canadian Asthma, Allergy and Immunology Foundation (CAAIF). Her lab is funded by federal and non-federal sources including CIHR-ICRH and industry.
