Paulness: He is co-founder of VGX....so if he ever leaves academia I would assume it would be to go to the company he helped to found. But I doubt he'd leave the Univ of Penn, he's got the best of both worlds. A world class lab, brilliant research staff, and an outside private company that's starting to make some progress. He's internationally recognized in the field. We need a businessman at the helm. Not an academic.
