How To Become Part of Desensitization Program

From the research that I've done I've found that there are desensitization studies happening at some U.S. locations including Duke University Medical Center and Arkansas Children's Hospital. I am interested in enrolling my son in one of the studies (preferably the Duke University program) but how do you "get into" the program. I will be focusing more on this aspect over my next postings. I'm not sure how to do this, but I feel this is the best solution considering that as Christopher gets older, it will become more difficult for him to totally avoid peanuts as society currently exists.
