Judith Blau (born April 27, 1942) is an American sociologist and professor emerita of the University of North Carolina at Chapel Hill.

[1] Blau taught at Baruch College as an assistant professor from 1973 to 1976, held a post-doctoral fellowship at Albert Einstein College of Medicine (1976–1978), taught at the State University of New York at Albany (1978–1982), and the University of North Carolina at Chapel Hill (1982–2013) where she founded and chaired the Social and Economic Justice minor[1][2][3] within the Sociology department.

Physicists had early access to the internet, allowing them to participate in international scientific exchanges, in defiance of the Cold War.

She has worked in several sociological specialties, and gradually discovered that she could wed her passion for social and economic justice with the same scholarly discipline she brought to her study of communications among scientists.

[20] Human Rights: Beyond the Liberal Vision, co-authored with Alberto Moncada, is a book that critiques American society.
