After receiving his B.A. from Johns Hopkins University (at age 18) and his J.D. from Boalt Hall School of Law of the University of California, Berkeley (at age 21), Greenberg served as law clerk to the Honorable Ruth Bader Ginsburg on the United States Court of Appeals for the District of Columbia Circuit.

Before coming to UCLA, Greenberg taught at Princeton University and the University of Oxford.

During this period, he also worked as a federal prosecutor. Greenberg has written numerous articles and book chapters. His article, “How Facts Make Law” won the American Philosophical Association’s 2007 Berger Memorial Prize for work in philosophy of law published in 2004 and 2005, and his article, “The Meaning of Original Meaning” (co-authored with Harry Litman) was the runner-up for the 2001 Berger prize.
