Reed Brodsky, a Southern District assistant U.S. attorney who has played a prominent role in high-profile insider trading prosecutions, is expected to join Gibson Dunn & Crutcher in coming weeks, according to several news reports. Brodsky, 43, is one of the government lawyers responsible for securing the convictions of Galleon Group hedge fund founder Raj Rajaratnam and former Goldman Sachs director Rajat Gupta.

A graduate of Vanderbilt Law School, Brodsky joined the federal prosecutor’s office in Manhattan in 2004 after a seven-year stint working on securities enforcement and white-collar defense cases in Washington, D.C., first with Crowell & Moring and later with Wilmer Cutler Pickering Hale and Dorr.

Andrew Michaelson, who worked alongside Brodsky on the Rajaratnam case before joining Boies, Schiller & Flexner as a partner, calls his former colleague a hard-working trial lawyer with a meticulous approach to mastering the evidence of a case. “He understands courtroom dynamics,” Michaelson added. “And there’s an overarching strategy to what he does. He’s got the big picture in mind.”

Randy Mastro, the Gibson Dunn partner who wooed Brodsky to the firm, said the firm has an upcoming busy trial schedule and he expects Brodsky to contribute immediately on a range of cases—not just those involving white-collar crime. The cases, all in the Southern District, include defending Moody’s against a lawsuit challenging ratings given a structured investment vehicle during the economic downturn; defending Apple in an antitrust case over its alleged price-fixing of ebooks; and representing Chevron in its long-running litigation over a $19 billion judgment awarded against the oil giant in Ecuador.

Neither Brodsky nor a spokeswoman for the U.S. attorney’s office would comment.
