Ever since the famous 1992 work of Bayer and Diaconis, it has been known that random shuffles of a deck of cards (with the back side up) can be modelled as elements of the group algebra $\mathbb{R}[S_n]$ of the symmetric group $S_n$. This viewpoint has spawned progress in both card shuffling and the representation theory of the symmetric group. In this talk, I will focus on two projects in the lat
