Positroid varieties are intersections of cyclically rotated Schubert varieties in the Grassmannian, introduced in my work with Knutson and Speyer. I will discuss some aspects of these very nice spaces, including a recent computation of the cohomology of open positroid varieties in joint work with Galashin.
