Former Wilson Sonsini Goodrich & Rosati securities litigator Bruce Vanyo, who encountered conflict issues a month after starting a new job at Kirkland & Ellis, was in Chicago Wednesday signing up with his third law firm of the year, Katten Muchin Rosenman.

He joins the firm’s Los Angeles office and will co-chair its securities litigation practice. He will also serve as a member of the firm’s board of directors.
