<p>Michigan, like other big state universities, is aided by its medical school and its affiliated hospitals. MIT is the best in terms of impact per paper (just behind Rockefeller). MIT biology has only 60 biology faculty members but has the funding surpassing Harvard Medical School, and ranks 8 in life science in productivity. Many of its biology faculties are the leaders in their fields (if shamelessly counting those awards: 4 Nobels, 32 NAS in just biology department), regularly publishing papers in top journals scuh Science, Nature, Cell. It is hard to beat. MIT is the dream school for me, period.</p>
