Dame Emma Natasha Walmsley DBE (born June 1969) is the chief executive officer (CEO) of GSK plc.

[5] She boarded at St Swithun's School, Winchester,[4] and has an MA in Classics and Modern Languages from Oxford University, where she was at Christ Church.

[9] At the time of her move to GSK in 2010, Advertising Age quoted company insiders surprised at her departure from L'Oreal, where she had been tipped for one of the most senior global management roles.

However, industry analysts noted that GlaxoSmithKline's decisions to hold its dividend would restrict the amount of cash available for R&D and acquiring intellectual property from other companies.

"[16] In January 2018, it was reported that Walmsley had replaced 50 of GlaxoSmithKline's top managers across the company's businesses, and created a number of new roles, including hiring Karenann Terrell from Walmart as chief digital and technology officer.

[17][18] Walmsley was appointed Dame Commander of the Order of the British Empire (DBE) in the 2020 Birthday Honours for services to the pharmaceutical industry and business.

[20] A Financial Times profile of Walmsley in September 2016 reported that colleagues describe her as a "strong and dynamic" leader who mixes a personable style with a "steely" focus.
