As chair of the BP America board, she focused on setting strategic direction and oversight of material risk across the 350 US subsidiaries.

Between 2015 and 2018, Dio was CEO of BP Shipping, which manages the fleet of BP-operated and chartered vessels moving over 200 million tons of products across the globe each year. In that London-based role, she reset the organization’s strategy and operations while also modernizing the company’s fleet, delivering 26 new, highly efficient tankers.
