Mark Lee, a former prosecutor who chaired Schnader Harrison Segal & Lewis' white-collar defense and corporate investigations group, has moved his practice to Blank Rome.

Lee joined Blank Rome as a partner in its white-collar defense and investigations practice in Philadelphia, the firm announced Tuesday.

He had a long history at Schnader Harrison, having started there as an associate in September 2006. He left the firm in 2011 to serve as an assistant U.S. attorney for the District of Delaware, and then returned to Schnader Harrison in 2015 as a partner.
