Dr Phillippa Diedrichs

About me

Dr Phillippa Diedrichs is a research psychologist with an international reputation for creating and using evidence-based strategies to improve body image in community, education, corporate, and policy settings on a local, national, and global scale.

​​With a PhD in Health Psychology from the University of Queensland (2011, ​Australia), she is passionate about working in partnership to create environments that accept diversity in appearance and support people, particularly girls and women, to live free from the constraint of appearance concerns. 

As an Associate Professor at the Centre for Appearance Research​, she leads a team of researchers investigating psychological and social influences on body image, and the development and evaluation of online and face-to-face body image interventions, advocacy efforts, and campaigns. ​

The evidence-based body image programmes that she has co-created and evaluated have been delivered in 136 countries to over 8.5 million young people through multi-stakeholder partnerships with global youth organisations and business. Her research has garnered international media attention and awards, and is published in esteemed, academic peer-reviewed journals. 

Dr Diedrichs regularly consults with businesses, agencies, and organisations on research, communications, campaigns, and advocacy. She has advised and worked on projects alongside the British Government Equalities Office, Unilever's Dove Self-Esteem Project, Transport for London, YMCA, the World Association for Girl Guides and Girl Scouts, Edelman, and Ogilvy. Dr Diedrichs regularly provides invited comment for media (e.g., Time Magazine, BBC, Vogue, ​Huffington Post, Men's Health, The Guardian) on issues relating to body image, disordered eating, and weight-based discrimination.​
