Abstract. I will describe boundary conditions for fermions in d=1+1 dimensions, using the framework of boundary conformal field theory. I will explain how boundary states are classified by a mod 2 index, related to their SPT phase, describe how one can follow RG flows from one boundary state to another, and give a novel perspective on the Z_8 classification of d=2+1 SPT phases.
