With new co-chairs leading the firm, Arnold & Porter Kaye Scholer appointed Lauren Giordani as the firm’s first chief practice innovation officer, the firm said Tuesday. It also promoted Randi Weiss to chief business development and marketing officer.

The chief practice innovation officer role is the second C-suite position the firm added in recent months. The firm named chief operating officer Sean Howell as CEO last October, another new position at Arnold & Porter.
