Sankar Ghosh is an Indian-American immunologist, microbiologist, and biochemist, who is the Chair and Silverstein & Hutt Family Professor of the Department of Microbiology & Immunology at Columbia University Irving Medical Center.

[1] Ghosh is best known for his pioneering research on the activation of cellular responses via NF-κB, a transcription factor that plays a critical role in regulating the expression of a large number of genes involved in the mammalian immune system.

[4] He previously was elected a Fellow of the American Association for the Advancement of Science in 2007 for his "distinguished contributions to the field of immunology, particularly for studies of the NF-kB signaling pathway.

Ghosh was instrumental in identifying, cloning and characterizing key components of the NF-κB pathway and his research led to the publication of multiple papers in leading scientific journals, including Nature, Cell, and Science.

After his success at the Baltimore lab, Ghosh began his independent research career at Yale University School of Medicine in 1991, serving as a professor in the Departments of Immunobiology and Molecular Biophysics & Biochemistry.
