HHMI has drawn significantly from outside the biological sciences for its latest class of investigators. The group comprises 32 men and 11 women from 31 institutions nationwide. Many represent traditional biomedical research disciplines, but nearly 25 percent received their primary training in areas such as chemistry, physics, computer sciences, engineering, and geobiology.

The four scientists below are representative of the group, both in the sense that they approach the scientific enterprise from unique perspectives, and in the way they work deftly across disciplines.
