Bio

Christopher Yoo has emerged as one of the nation's leading authorities on law and technology. [More]
Christopher Yoo has emerged as one of the nation's leading authorities on law and technology. His research focuses primarily on how technological innovation and economic theories of imperfect competition are transforming the regulation of the Internet and other forms of electronic communications. He has been a leading voice in the debate over “network neutrality” that has dominated Internet policy over the past two years. He is also pursuing research on copyright theory as well as a historical project on presidential power.

Yoo is the co-author of forthcoming books on the regulation of telecommunications (Cambridge University Press) and on the history of presidential control over the administration of the law (Yale University Press). He has authored more the two dozen articles and book chapters, published in the Columbia, New York University, University of Pennsylvania, Cornell, and Northwestern University Law Reviews among others, as well as the Harvard Journal of Law and Technology and the Yale Journal on Regulation. He is a frequent lecturer on technology-related topics, presenting his research at such leading universities as Yale, Columbia, Berkeley, Michigan, Virginia, Cornell, Georgetown, and UCLA, and at scholarly conferences. Yoo has frequently been asked to testify before Congress and leading regulatory agencies, such as the Federal Communications Commission and the Federal Trade Commission.

Before joining the Penn faculty in 2007, Yoo served as Professor of Law and the Founding Director of the Technology and Entertainment Law Program at Vanderbilt University. Prior to that, he clerked for Justice Anthony M. Kennedy of the Supreme Court of the United States and Judge A. Raymond Randolph of the U.S. Court of Appeals for the D.C. Circuit. He also practiced with the law firm of Hogan & Hartson in Washington, D.C., under the supervision of now-Chief Justice John G. Roberts, Jr.
