Peter is a seasoned litigator who has tried more than a dozen cases and argued more than fifteen appeals.  He focuses his practice on white collar defense, corporate internal investigations, and complex civil litigation.  Peter served from 2004 until 2015 as an Assistant U.S. Attorney in the U.S. Attorney’s Office for the Southern District of New York. 

Since joining the firm, Peter has handled a wide variety of high-profile criminal and civil matters, representing clients in DOJ, SEC and other regulatory investigations; overseeing headline-grabbing antitrust cases–both for defendants and plaintiffs; and representing tech startups in litigations challenging the sharing-economy business model.

At the U.S. Attorney’s Office, Peter was a senior prosecutor in the Terrorism and International Narcotics Unit and the Organized Crime Unit.  He had extensive experience prosecuting international money-laundering crimes and helped develop the prosecution of trade-based money-laundering.  Peter also frequently investigated global and domestic criminal organizations for RICO violations and oversaw three RICO trials. In leading numerous global investigations, Peter regularly coordinated with law enforcement officials in Europe, Asia, Latin America, and the Middle East. 

In addition to his work as a criminal prosecutor, Peter served for four years in the Civil Division of the U.S. Attorney’s Office, where he advised the intelligence community on litigation affecting national security and handled a variety of complicated civil matters, including False Claims Act, bankruptcy, and environmental cases.
