Imagine bright young things entering a new kind of science PhD, in which both they and their supervisors embrace from the start the idea that graduates will go on to an array of demanding careers — government, business, non-profit and education — and work towards that goal (see page 381). The students meet supervisors from a range of disciplines; they acquire management, communication, leadership and other transferable skills alongside traditional academic development of critical thinking and analysis; and they spend six months to a year abroad.
