C. Scott Hemphill, a Columbia Law School professor and former clerk to U.S. Supreme Court Justice Antonin Scalia, has been hired to run Attorney General Eric T. Schneiderman’s antitrust bureau. Mr. Schneiderman said that Mr. Hemphill’s “expertise in the complex area of antitrust law is broad and deep, as is his commitment to justice and fairness. He will be a tremendous asset to this office, and the people of New York State.”

Mr. Hemphill, a Phi Beta Kappa graduate of Harvard who also has a master’s degree in economics from the London School of Economics and Political Science, a law degree from Stanford—where he edited the law review—and a doctorate in economics from Stanford, clerked for Justice Scalia in 2003 and 2004.
