Dr. Galit Alter is a Professor of Medicine at the Ragon Institute of MGH, MIT and Harvard. After completed her BSc and PhD at McGill University in the arena of HIV infection and pathogenesis, Dr. Alter shifted her work to the development of technologies to study the human immune response across pathogens. Dr. Alter’s work focuses on the development of systems biology tools to define the correlates of immunity against infectious diseases that ravage the globe including HIV, malaria, Tuberculosis, Ebola, Influenza, and many others. These efforts have been accelerated by the development of a unique Systems Serology profiling approach, which enables her to comprehensively dissect the immune response, enabling the identification of pathogen- or vaccine-specific humoral immune responses at an unprecedented depth. Coupled to machine learning and artificial intelligence, her work unveils the mechanistic basis of protective immunity across pathogens, often pointing to unexpected correlates of humoral immunity against infection.
