In 2008, as Chair, President & CEO of Sunoco, Inc. and Sunoco Logistics Partners LLC (2008-2012), she became the first woman to lead a major U.S. oil company. She drove a decisive strategic pivot: exiting refinery operations, focusing on high-return logistics and fuel marketing, and orchestrating a successful corporate simplification and recovery of shareholder value.

She is widely recognised for her pioneering 28-year tenure at Royal Dutch Shell, including leadership roles as Executive Vice President of Shell Downstream Global Manufacturing, President & CEO of Shell Oil Products USA, and Regional CEO for Asia Pacific & Middle East — positions in which she oversaw refining, petrochemicals, logistics and large-scale operations across North America, Europe, and Asia.

She brings deep cross-sector expertise in:

• Energy & industrial operational leadership – leading global refining, petrochemical, and logistics platforms with rigour and systems discipline

• Strategic transformation & divestiture – directing major portfolio realignment at Sunoco and Shell under complex market environments

• Board governance & risk oversight – Serving on high-profile international boards spanning energy, engineering, life sciences and downstream manufacturing

• Governance in emerging markets – navigating new roles with Saudi Aramco and TSMC, combining governance expertise with cross-border insight
