Philosophers of Qualia

Enwe asks: "Imagine there is a PhD student who will write a dissertation about qualia and asks you, as his supervisor, what he should read. What would you suggest?" She mentions Chalmers, Dennett, and Dretske, to begin with. Note that Enwe has a friend about to begin a dissertation on just this topic, so it would be very helpful if you could head on over and add any further suggestions.
