Based in the company’s offices in New York City, Davitt will lead the US expansion of the practice, which specialises in applying behavioural principles in the luxury retail sector.

Davitt (pictured) was most recently vice-president at Kantar Insights, where she led global client relationships.

PRS In Vivo aims to promote the emerging science of happiness as a key factor in sustainable customer relationships for luxury brands.

Anne-Laure de Broissia, senior vice-president and global head of the PRS In Vivo luxury practice, said: “Davitt brings with her a well-deserved reputation for exceptional client service, a strong sense of style and trends in beauty, cosmetics and fashion, as well as a keen understanding of the challenges facing the luxury retail sector.”
