John Huber is Professor of Political Science at Columbia University. He received his Ph.D. from the University of Rochester in 1991, and was on the faculty at Michigan for six years before joining Columbia in 1998. With Charles Shipan, he recently published Deliberate Discretion? Institutional Foundations of Bureaucratic Autonomy (Cambridge), which develops and test a comparative theory of delegation in advanced democracies. Huber's current research projects examine individual turnover among cabinet ministers in parliamentary democracies; the effects of bureaucratic capacity on delegation strategies; and the impact of legal structure on policymaking venues.
