New York-based mergers and acquisitions lawyer Barbara Becker is set to become Gibson, Dunn & Crutcher’s first female managing partner, after the firm’s partnership elected her Wednesday to replace longtime leader Ken Doran.

When she steps into the position in May, Becker—who currently sits on the firm’s executive committee and chairs its diversity committee—will join just eight other women now in top leadership roles at Am Law Global 50 firms.
