This is part of joint projects with Michael Ehrig and Ge Li. We consider Brauer algebras and their representation theory in the nonsemisimple cases. We formulate a Schur-Weyl duality statement with the orthosymplectic Lie superalgebra and then connect it with the category O for classical so(n). As an application one obtains gradings on Brauer algebras. Finally we will briefly explain the graded branching rules via some action of a coideal subalgebra inside a quantum group. This coideal subalgebra is a quantum analogue of quantum symmetric pairs.
