Description: Consider the secant variety to an embedded smooth variety in some projective space. I will show if the associated line bundle is sufficiently positive, then the secant variety is Du Bois, but not rational in general. Then I will consider general normal varieties, and explain how the consideration on direct images of twisted canonical bundles from resolutions may lead to a new measurement of the singularities.
