Hopefully-
The top scientists would be part of it and so would the new subjects
The top scientists would include specific types of scientists, though each one would probably have quite a few different areas of study/expertise, so like-
A chemist that actually worked to develop the thing
A neurologist/psychologist/etc that's making sure it doesn't do anything terrible there
A physician/biologist/etc that's making sure it doesn't do anything terrible to the body
And, like, a head of reasearch. Probably.
