Contact loci are singularity invariants related to jet and arc spaces and the Milnor fiber. Several of their additive properties are known by using motivic integration. However, very little is known about the non-additive properties of these objects, such as their cohomology. In this talk we will present some work-in-progress techniques to compute the cohomology of contact loci, and apply these techniques to the case of plane curves with one Puiseux pair.
