I can give you one right now. Dr. Chris Busby testified before the Italian Parliament and in Britain as well with regard to the Stuart Dyson case. You will see his name quite a bit on the Internet if you Google. He has done exceedingly well in his research, and his CV is pages and pages long. He is on many committees.
The other one is Dr. Asaf Durakovic. He won a Nobel Prize for his study of depleted uranium. He also is published in the Croatian Medical Journal as well as many other periodicals.
Those are two I can give you off the top of my head who we correspond with on a fairly regular basis.
