Starting in January 2015, he oversaw the division's Office of Broker-Dealer Finances, Office of Derivatives Policy, Office of Trading Practicies, and its Volcker rule team, along with its participation in various global regulatory initiatives. In addition, he has been a member of the agency’s Cybersecurity Working Group and its Fintech Working Group and has been its senior most representative on multiagency groups including the Senior Supervisors Group and the Supervisors Roundtable on Governance Effectiveness.

The SEC on December 15, 2017 announced that Barnett would retire from the agency at the end of the year.
He was previously the director of the Commodity Futures Trading Commission's (CFTC) division of swap dealer and intermediary oversight, the department responsible for registration and compliance of exchanges and self-regulatory organizations, as well as business conduct standards, capital adequacy, and margin requirements for swap dealers and major swap participants. He was appointed to the position on Aug. 22, 2011.  The division was created as part of the CFTC's additional duties related to the Dodd-Frank Act, which will require the agency to monitor the previously-unregulated swaps market.
Barnett left the CFTC in December of 2014 to join the SEC.
Before joining the CFTC, Barnett was a law partner in the New York office at Linklaters LLP, where he headed the U.S. derivatives and structured finance group. In this role, he led the development and implementation of clearing systems for the derivatives market and regulatory reforms affecting the derivatives and securitization markets. Before joining Linklaters, he was co-head of the securitization and derivatives practice at Shearman & Sterling LLP. Barnett's previous experience included partnerships at law firms O'Melveny & Myers and Cadwalader, Wickersham & Taft.
Barnett is an adjunct professor of law at Cornell University, Ithaca, NY. Additionally, he serves as co-chair of the Practising Law Institute's annual conferences on fundamental and advanced swaps. Prior to joining the CFTC, he chaired the annual PLI conference on new developments in securitization for more than 15 years.
Barnett is a member of the New York, California and Oklahoma bar associations.
Barnett participated in the MarketsWiki Education World of Opportunity series in New York in July of 2017.
