Maybe you could talk about how people with ASD seem to have an interest that it becomes part of them and their everyday life. It's generally a feel good factor about how life goes on and how we continually deal with it.
Guest wise, I'd go for psychologists and medical staff...
I just think that with the whole Dr. thing, I presume it is for medical advice.
If so then have you considered talking to the general public about any issues and ask what you can think of such... try to put yourself in their shoes, see it from their perspective.
