I start by giving an introduction to IETs, translation flows, and the notion of renormalization. Then I motivate and define the rather new concept of twisted cocyle (originally defined by Bufetov and Solomyak). I will then discuss the existence of zero exponents and the problem of non degeneracy of the spectrum for the twisted Cocycle depending on the combinatorial data of the IET. This is based on joint work with Hesam Rajabzadeh
