I have little more then a keen internet searching ability, but I offer the following:
1. To achieve any sort of credible status in the publishing of medical research I suspect AT MINIMUM that one must be an MD. Certainly, uncredited or minially credited contributions are available for others, and your level of required recognition is something only you can decide.
2. I went to the jhu.edu job search website
here and selecting the two "research" related "areas of interest" [those being Laboratory/ Technical/ Technical Research Support ~and~ Research Support (non-lab)]. I found 305 job listings.
You should check out the various fields, locations, and position requirements.
I must admit I am very curious about these restrictions you mentioned have been placed on your education and career potential, and wish you would expand on them.
Good luck,
