My predecessor as Science Adviser, Dr. George Atkinson, created an opportunity for tenured academic scientists and engineers, farther along in their careers than the typical AAAS fellow, to work as science diplomats in the State Department. Jefferson Fellows come to the State Department for a year, funded by their own university, as they would be on a sabbatical leave, with the State Department covering their local living and travel expenses. Fellows then consult for the State Department for an additional 5 years after they return to their home institutions. The Jefferson Fellows program was initially launched with grants from the Carnegie Corporation and the MacArthur Foundation. It is now part of the State Deparment and is administered by the National Academy of Sciences.
