Around '98, Tamarkin derived the formality of the little disks operad from the existence of a Drinfeld associator. Later on, Kontsevich extended this result to higher dimensions through a different approach. The aim of my talk is to explain a generalization of Tamarkin's original approach to higher dimensions. This generalization relies on Igusa's construction of higher holonomies for flat superconnections. The talk is based on ongoing joint work with Camilo Arias Abad.
