Matthew Martens, the former chief litigation counsel of the Securities and Exchange Commission who recently led the government’s successful prosecution of ex-Goldman Sachs bond trader Fabrice Tourre, has joined Wilmer Cutler Pickering Hale and Dorr as a securities and litigation partner in New York.

“Matt is an excellent securities lawyer and first-rate trial lawyer,” former SEC enforcement chief and Wilmer’s securities department chair William McLucas said in a statement. “As the stakes continue to get higher in regulatory enforcement matters generally, his experience and abilities as a litigator will be invaluable to our clients and will strengthen our practice group enormously.”
