Hanah Margalit never left Israel.
Margalit completed postdoctoral research at the National Institutes of Health (NIH) in the laboratory of mathematical biology under the supervision of Charles DeLisi, where she developed the first computational algorithm to predict antigenic peptides recognized by immune cells. The National Institutes of Health (NIH) (/n.a.et/) is the primary agency of the United States government responsible for biomedical and public health research. In 1989, she returned to Israel and established her independent research group at the Faculty of Medicine, the Hebrew University of Jerusalem. The majority of NIH facilities are located in Bethesda, Maryland and other nearby suburbs of the Washington metropolitan area, with other primary facilities in the Research Triangle Park in North Carolina and smaller satellite facilities located around the United State.
