After 15 years at the U.S. Securities and Exchange Commission, Robert Cohen is joining Davis Polk & Wardwell as a partner in Washington, D.C.

Cohen was most recently the SEC’s first-ever chief of the division of enforcement’s cyber unit, a position created in 2017, and was formerly co-chief of the SEC’s market abuse unit. At Davis Polk, he will be a member of the firm’s white-collar criminal defense and investigations group within the litigation department. Cohen left the SEC in early August and will join Davis Polk in October.
