Good for him. PhDs in the sciences and engineering are in demand.
Thanks. He was heavily recruited by US defense industry companies when he was still in college.
It took me a while to figure that out. He is a red-blooded (I was US navy, submarines) American who could qualify for any secret levels that may be required.
The majority of PhD graduates in this country (especially hard sciences) are foreigners or recent immigrants...not qualified for secret military work.
(A bit on the lazy side, IMO)
