Ai Ing Lim is an incoming Assistant Professor of Molecular Biology at Princeton University. Originally from Malaysia, she received her master’s degree from The University of Hong Kong. As a European Union Marie Curie Fellow, she completed her graduate studies at Pasteur Institute (Paris), under the mentorship of Prof. James Di Santo. There, she identified innate lymphocyte precursors from the blood and tissues of healthy individuals. With the support of Human Frontier Science Program fellowship, she joined the laboratory of Dr. Yasmine Belkaid at the National Institutes of Health for postdoctoral training. During her postdoctoral training, she found that maternal infection can provide pre-birth immune education to the offspring in a tissue-specific manner. Together, her works in both human and murine immunology demonstrated that the immune system is highly plastic and can adapt to environmental challenges even before birth. Her contributions were recognized as an International Rising Talents by the L’Oreal-UNESCO, the best European Immunology Thesis (ACTERIA Doctoral Prize) by the European Federation of Immunological Societies, the Sidney & Joan Pestka Post Graduate Award by the International Cytokine and Interferon Society.
