Fellow, Thurman Arnold Project, Yale University
Dina Srinivasan is a researcher, lawyer, and entrepreneur. She’s also a Fellow with the Thurman Arnold Project at Yale University.
Most recently, Ms. Srinivasan’s research and economic analysis of new, tech markets provided the foundation for government enforcement of antitrust laws against two of the largest market cap companies in the world. Her 2020 research, "Why Google Dominates Advertising Markets: Competition Policy Should Lean on the Principles of Financial Market Regulation", explains how Google distorts electronically traded ad markets by engaging in conduct that lawmakers normally prohibit (e.g., conduct analogous to insider trading and front running). Her research instigated a shift in the House and Senate and a coalition of U.S. States subsequently filed suit against the company relying on the architecture of Ms. Srinivasan’s thinking. "The Antitrust Case Against Facebook", published in 2019, laid out the correlation between privacy and economics. Congress called on the U.S. Federal Trade Commission to open an investigation; and in 2020, the Federal Trade Commission and a coalition of 48 Attorneys General filed actions against Facebook. She’s been profiled by The New York Times and The Wall Street Journal. Her research and commentary on tech and competition are regularly covered in the domestic and global media.
Previously, Ms. Srinivasan founded an ad technology company whose technology was acquired by a division of WPP, Kantar Media SRDS (NASDAQ). She spent four years as an executive at WPP. In the late 1990s, she founded iMSGu, a text messaging platform that allowed users to send messages across different mobile spectrum networks (CDMA, TDMA, GSM); the company folded in 2002. Ms. Srinivasan holds a J.D. from Yale Law School, where she studied law & economics and was an Olin Fellow with the Kauffman Program in Law, Economics and Entrepreneurship. She lives in the Bay Area with her husband and their four children.

Ryan co-founded and is a past president of the Downtown Club of Oklahoma City, and previously served on the Board of Trustees of the Oklahoma City National Memorial, the Board of Directors of the Central Oklahoma Red Cross, the Central Oklahoma YMCA and KIPP Charter School, the Executive Committee of the Board of Directors for the Oklahoma Academy of State Goals, the Legal Ethics Committee of the Oklahoma Bar Association and was a member of Leadership Oklahoma Class XIX. Ryan has also volunteered his time pro bono for Oklahoma Lawyers for Children, serving children at risk in the foster care system. At a younger age, Ryan earned the rank of Eagle Scout.
In 2008, Ryan was appointed by the Governor as a Commissioner representing the State of Oklahoma on the national Uniform Law Commission, and was reappointed in 2014 and 2018. In 2015, Ryan was appointed by the President of the national organization to the Executive Committee, and as chair of the national Legislative Council. Ryan has served on numerous committees within the organization, including drafting committees implementing the Hague Convention on Choice of Court Agreements (facilitating international contracts) and drafting a Model Tribal Probate Code. Ryan co-chairs the Committee on Attendance, and serves on the Committees on Scope and Program and State and Federal Relations.
Through his law practice, Ryan is also regularly appointed by multiple Courts as a “Receiver” over troubled businesses, tasked with either managing, rehabilitating, or liquidating the business for the benefit of creditors. In 2018, at the request of the Oklahoma Insurance Commissioner, the Oklahoma County District Court appointed Ryan as “Interim CEO” of Union Mutual Insurance Company, an Oklahoma-domiciled insurance company, that was successfully rehabilitated and emerged from receivership. Ryan served as Interim CEO for a period of six months during which time he identified and installed a permanent corporate leadership team. In addition, in 2019, Ryan was appointed by the U.S. District Court for the Western District of Oklahoma to serve as Chairperson of a three-member Commission to assist the Federal Court in determining just compensation to multiple landowners in a federal eminent domain pipeline action.
In 2020, Ryan was hired by Oklahoma Governor Kevin Stitt to serve as his Special Counsel for Native American Affairs. In this capacity, Ryan assists the Governor and his administration on issues arising from the U.S. Supreme Court’s recent decision in McGirt v. Oklahoma, through which the Court ruled the Creek Nation reservation still exists within the State of Oklahoma for purposes of criminal jurisdiction.
In January 2021, as authorized by Oklahoma law, Governor Stitt designated Ryan as the lead negotiator for the state in the discussions with Oklahoma's Native American tribes to address the foundational jurisdictional issues raised by the McGirt decision.
Ryan earned his law degree from the University of Oklahoma, and graduated magna cum laude from Boston College. Ryan also attended the L’Institut d’Etudes Politiques in Strasbourg, France. In his spare time, he enjoys coaching his children's activities, reading history, travel and archaeology. He is the co-author of “Opala: In Faithful Service to the Law,” a biography on former Oklahoma Supreme Court Justice Marian Opala, as well as "Principles and Perseverance: The Life of Don Nickles."
Ryan is admitted to practice before the Oklahoma Supreme Court and all Oklahoma state courts, the federal courts of the Western and Northern Districts of Oklahoma, the 10th Circuit Court of Appeals and the United States Tax Court.
