Representations of braid groups of Lie type

I will discuss recent joint work with Toledano Laredo on the monodromy of the Casimir connection. The monodromy representation of this connection leads to a functor from representations V of a simple complex Lie algebra g to representations of the corresponding braid group of Lie type Bg ( on the zero weight space V[0] of V). I will discuss the problem of when this braid group representation is reducible answering a question of Procesi and Knutson. I will also give counterexamples using the same idea to a related conjecture of Kwon and Lusztig on representations of Bg coming from the quantum group associated to g.
