The Conferences normally distribute a list of the talks to be given and the conference schedule. Participants are also listed. If you can take the time, I'd look up some of the participants at the National Library of Medicine (Pubmed) and see what subjects appear in papers they've published. Then be guided by what you see.
If you have the chance, I would certainly recommend that you attend any session where Ken Casey is to speak. He's both very knowledgeable and very gracious in talking with patients. Also of interest will be any session where Dr. John Tew speaks (assuming he's at the conference). Like Ken, he is a long-time colleague of Peter Janetta and extremely knowledgeable. If you have a link to the conference agenda, send it along. I'll be happy to make further suggestions.
