I’m proud to work on behalf of the victims of corporate fraud and abuse alongside such talented and tireless colleagues.


Jonathan Zweig is a partner with Robbins Geller Rudman & Dowd LLP and is based in the Manhattan office. Jonathan’s practice focuses primarily on complex securities litigation, corporate control cases, and breach of fiduciary duty actions on behalf of investors. 

Before joining Robbins Geller, Jonathan served for over six years as an Assistant Attorney General with the New York State Office of the Attorney General’s Investor Protection Bureau, where he prosecuted civil securities fraud actions and tried two major cases on behalf of the State. In New York v. Exxon Mobil Corporation, a high-profile securities fraud case concerning climate risk disclosures, Jonathan examined numerous witnesses and delivered the State’s closing argument at trial. In New York v. Laurence Allen et al., Jonathan and his colleagues achieved a sweeping victory at trial for defrauded investors in a private equity fund, and established for the first time the retroactive application of the Martin Act’s expanded statute of limitations. Jonathan also conducted data-intensive investigations of Credit Suisse concerning its alternative trading system and its wholesale market making business, resulting in joint settlements with the SEC totaling $70 million from Credit Suisse. On three occasions, Jonathan was awarded the Louis J. Lefkowitz Award for Exceptional Service. 

Jonathan was previously a litigator at Davis Polk & Wardwell LLP, where he represented clients in securities litigation, mass tort, and other matters. Jonathan also clerked for Judge Jacques L. Wiener, Jr. of the U.S. Court of Appeals for the Fifth Circuit, and Judge Sarah S. Vance of the U.S. District Court for the Eastern District of Louisiana. 

Jonathan earned his Bachelor of Arts degree, summa cum laude, in history from Yale University, and earned his Juris Doctor degree, magna cum laude, from Harvard Law School.
