Lynne began her career as an Chartered Accountant when she trained with Arthur Andersen and Co. She moved into the corporate world, working for many years with Tate & Lyle plc, where she had several financial leadership roles. She also worked on major integrations and mergers, which led her to join Cancer Research UK at its formation in 2002. She was Chief Financial Officer for 11 years, leading the technology, property, risk, finance and Treasury teams. Her interest in leading change meant she was involved in many developments there, including the Francis Crick Institute. Recently, she also worked with the YMCA, in a strategic support role to the CEO and Board.
