One of the biggest challenges facing young scientists today is the extreme competition for positions at researching universities and delayed (if at all) job security. In America only 57% of doctoral students will have a PhD ten years after their first date of enrollment. (Economist
) Even more grim is the fact that only 12.8% of those PhD students actually end up as a tenured professor. (Larson 2013
) Out of every 1,000 science PhD grads, only around 45 of them end up a full-time professor at a research university.
