We may be able to make Vidya Setlur's slides public, which will simplify things. But in the meanwhile, I've created a group that you can join to view the slides.
Click here to request admission to the group and be able to view the slides. I will have to grant you permission to join. Once you have joined the group, you can view the slides here.
Updated: Vidya has had to change to a non google format because of a size limit on the native format. You can get access to it here.
