Homeward bound: Princeton engineers promote science in their native countries .

The stories that Edgar Choueiri and Winston Soboyejo tell of their native countries and of their own careers are strangely similar. These two Princeton engineering professors came from societies where science blossomed for a time and then atrophied. Both left their native countries to earn their scientific credentials. And now both men find themselves drawn home again to give something back to the societies where they were first inspired.
