Christopher S. Yoo is the John H. Chestnut Professor of Law, Communication, and Computer and Information Science at the University of Pennsylvania Law School, and the founding director of the Center for Technology, Innovation, and Competition. He is well known for his work on technology law, media law and copyright, and is among the most frequently cited authors in that domain.^[1] He is best known for being among the first academics to engage in the debate over network neutrality. He has taken a middle ground between a more restrictive and more permissive approach, animated by the belief that innovation needs room for experimentation if it is to thrive. He characterizes his position as network "diversity," which argues that the technology and economic environment surrounding the Internet requires greater flexibility, with the difficult question being how much flexibility is too much. He has also studied the history of the unitary executive in the United States.
