Jean Sylvia Marshall, born in Birmingham, England, is a Canadian immunologist and acting Professor and Head of the Department of Microbiology & Immunology at Dalhousie University in Halifax, Nova Scotia, Canada.[1] Marshall's work has investigated how mast cells are involved in the early immune response to infection and antigen. She is best known for her discovery of the previously unknown degranulation-independent immunoregulatory roles of mast cells in infection and allergy and their ability to mobilize dendritic cells.[2]
Marshall's current research relates to studying innate immunity and local immune events and environment. Her work spans many fields, including immunology, inflammation, allergy, mast cell biology, chronic inflammatory disease, innate immunity, and cancer biology (specifically breast cancer). her lab also has a special interest in toll-like receptors in mucosal immune regulation.
