As a scientist, health economist, entrepreneur and business leader, Claire Gillis is passionate about using communications and connections to promote better access to healthcare. At the helm of the largest global health offering within WPP, she manages 2,000 health specialists and creatives across North America, Europe and APAC. Gillis developed the health economic argument for Gardasil that led the British government to introduce free access to HPV vaccines for girls, bringing a dramatic fall in cervical cancer rates in Britain and stimulating a movement to eradicate the disease worldwide. The U.K. program was extended to adolescent boys and is predicted to prevent 29,000 male cancers in the next 40 years.

Gillis is a director of the Developmental Therapeutics Consortium, an early oncology asset consultancy, and has been a non-executive director for InMed, a U.S. charity supporting disadvantaged families. Her current passion — and the topic of her master’s degree dissertation at Oxford University — is the reduction of racism in clinical trials.
