Segal Family Professor of Regulatory Law and Policy, New York University School of Law
Rachel Barkow is the Segal Family Professor of Regulatory Law and Policy and the Faculty Director of the Center on the Administration of Criminal Law at NYU. In June of 2013, the Senate confirmed her as a Member of the United States Sentencing Commission. Since 2010, she has also been a member of the Manhattan District Attorney's Office Conviction Integrity Policy Advisory Panel.
Professor Barkow teaches courses in criminal law, administrative law, and constitutional law. In 2013, she was the recipient of the NYU Distinguished Teaching Award. The Law School awarded her its Podell Distinguished Teaching Award in 2007.
Her scholarship focuses on criminal law, and she is especially interested in applying the lessons and theory of administrative and constitutional law to the administration of criminal justice. She has written more than 20 articles that span a range of topics. She has written several articles on sentencing, including the relationship between modern sentencing laws and the constitutional role of the criminal jury; federalism and the politics of sentencing; the role of cost-benefit and risk tradeoff analysis in sentencing policy; what institutional model works for designing agencies that regulate criminal punishment; the political factors that lead to guideline and commission formation; and the flawed bifurcation between capital and noncapital constitutional sentencing jurisprudence. Professor Barkow has also explored in numerous articles the role of prosecutors in the criminal justice system. For example, she has analyzed how the lessons of institutional design from administrative law could improve the way prosecutors' offices are structured; she has looked to organizational guidelines and compliance programs as a model for prosecutorial oversight; and she has considered the increasing role of prosecutors as regulators through the conditions they place on corporations. Professor Barkow has also explored larger structural questions of how criminal justice is administered in the United States. In a series of major articles, she has explored the relationship between separation of powers and the criminal law and the relationship between federalism and the criminal law. Professor Barkow has also considered the role of mercy and clemency in criminal justice, paying particular attention to the relationship between administrative law's dominance and the increasing reluctance of scholars and experts to accept pockets of unreviewable discretion in criminal law.
Barkow has been invited to present her work in various settings. In the summer of 2009, Barkow testified before the House of Representatives Subcommittee on Commerce, Trade, and Consumer Protection regarding the institutional design of the proposed Consumer Financial Protection Agency. Barkow testified before the United States Sentencing Commission at a 2009 regional hearing on the 25th Anniversary of the Sentencing Reform Act. In the summer of 2004, Barkow testified before the Senate Judiciary Committee at a hearing on the future of the Federal Sentencing Guidelines. She has also presented her work on sentencing to the National Association of Sentencing Commissions Conference, the Federal Judicial Center's National Sentencing Policy Institute, and the Judicial Conference of the Courts of Appeals for the First and Seventh Circuits. In addition, Barkow has presented papers at numerous law schools.
After graduating from Northwestern University (B.A. 1993), Barkow attended Harvard Law School (J.D. 1996), where she won the Sears Prize, which is awarded annually to two students with the top overall grade averages in the first-year class. Barkow served as a law clerk to Judge Laurence H. Silberman on the District of Columbia Circuit, and Justice Antonin Scalia on the U.S. Supreme Court. Barkow was an associate at Kellogg, Huber, Hansen, Todd, Evans & Figel, PLLC, in Washington, D.C., from 1998-2002, where she focused on telecommunications and administrative law issues in proceedings before the FCC, state regulatory agencies, and federal and state courts. She took a leave from the firm in 2001 to serve as the John M. Olin Fellow in Law at Georgetown University Law Center.
United States Senator, Tennessee
U.S. Senator Marsha Blackburn was sworn in to the Senate in January 2019. Marsha Blackburn was elected to the U.S. Senate in 2018, and is currently serving her first term representing the state of Tennessee. Before her election to the Senate, Marsha represented Tennessee’s 7th Congressional District.
Marsha’s public service is dedicated to promoting opportunities for women and making America a more prosperous place to live. Marsha’s leadership philosophy is based on her experiences in the private sector as a small business woman and author, as well as being a mother and grandmother.
Marsha went to college on a 4-H scholarship and worked her way through school selling books for the Southwestern Company as one of their first female sales associates, and later as one of their first female sales managers.
She then became Director of Retail Fashion and Special Events for the Castner Knott Company, which was a Nashville-based regional department store. Later, Marsha founded her own business, Marketing Strategies, which focused on the retail marketplace, as well as electronic and print media.
Marsha began her career in public service in 1995 when she was named executive director of the Tennessee Film, Entertainment, and Music Commission. In 1998, she was elected to the Tennessee State Senate. In the state legislature, she earned a reputation for fiscal responsibility and government accountability by identifying waste and offering realistic solutions to Tennessee’s budget challenges.
While serving in the Tennessee Senate, Marsha led a statewide grassroots campaign to defeat a proposed state income tax. The tax was defeated, and Marsha’s leadership earned her a reputation as an anti-tax champion. In 2014, the people of Tennessee passed an amendment to the state constitution to expressly prohibit a state income tax – a fitting cap to a 14-year battle.
In 2002, Marsha was elected to represent the people of Tennessee’s 7th Congressional District based on her record in the state legislature. She brought her Tennessee values to Washington, DC, and became a leader in the fight for small, efficient federal government that is accountable to its citizens. As a Congressman, Marsha was often selected by her colleagues to lead the charge for principled conservativism. Her congressional career was also noted for her Chairmanship of the Energy and Commerce Committee’s Subcommittee on Communications and Technology, as well as bipartisan expertise in defending songwriters’ and performers’ rights.
Marsha is a member of numerous charitable organizations and is an active member of her church, Christ Presbyterian.
Marsha and her husband Chuck live in Williamson County, Tennessee. They have two children, Mary Morgan (Paul) Ketchel and Chad (Hillary) Blackburn, and two grandsons. Originally from Laurel, Mississippi, Marsha is a graduate of Mississippi State University.
Partner, Boies Schiller Flexner LLP
Jesse, the former third-ranking official at the U.S. Department of Justice, helps clients with their most difficult litigation and regulatory issues─whether that means defending against an enforcement action, pursuing high-stakes litigation and appeals, navigating regulatory thickets at federal and state agencies, or crafting a comprehensive strategy to manage a crisis. He approaches these problems with the knowledge gained both from his broad private-practice experience and from having served at the highest levels of federal and state government.
Jesse has experience across a range of substantive and regulatory areas. He has sued the federal government and has also been one of its top law-enforcement officials; he has represented states and has also navigated their regulatory agencies on behalf of clients; and he has represented companies in business disputes, both as defendants and plaintiffs.
Before joining the firm, Jesse was the Acting Associate Attorney General at the United States Department of Justice. In that role, he oversaw the civil and criminal work of the Antitrust, Civil, Civil Rights, Environment and Natural Resources, and Tax Divisions.

In addition, Jesse served as Chair of DOJ’s Regulatory Reform Task Force and Vice Chair of DOJ’s Task Force on Market Integrity and Consumer Fraud. Jesse regularly provided legal and strategic advice to the highest-level decision makers in the federal government, including the Attorney General and Deputy Attorney General, general counsels across the spectrum of federal agencies, and White House officials.
Jesse served for three years as the secretary of Florida’s labor, economic-development, and land-use agency, the Florida Department of Economic Opportunity. Before that, he served as Governor (now Senator) Rick Scott’s general counsel.
Jesse maintains offices in both Washington D.C. and Florida. From Washington, he focuses on federal litigation and crisis management. In Florida, in addition to federal litigation, Jesse employs his knowledge of state government and regulation to help clients in courts across the state, from trial through the Florida Supreme Court.
