Cystic Fibrosis - a Nursing Specialty?

Is there anyone who is a nurse specializing in Cystic Fibrosis? If so how did you manage it (ie. are there specialized courses, or did you work on a CF unit, etc.) CF has affected my family greatly as my aunt was a spokeswoman for the CFF until she passed away at age 35. I am really interested in pursuing my career in this area, so any information available would be greatly appreciated!!

Thanks & Take Care
