social scientist on a mission

Hi, I’m Phillippa Diedrichs, PhD - a Professor of Psychology, academic, speaker, consultant, author, body image expert and mental health advocate.

I’m driven by a simple but radical vision: a world where no one is held back by appearance biases, exclusionary beauty ideals, gender stereotypes, or unjust systems - especially women, girls and gender-diverse people.

I work with purpose-led scientists, brands, organisations, and brilliant humans to make this vision a reality - combining the latest science with strategy, creativity and social impact.
