Centered around 75 cutting-edge laboratories working in a broad range of fields, The Rockefeller University fosters a collaborative research environment for its faculty and provides an innovative educational experience for its select group of outstanding graduate students and postdoctoral researchers. To help reduce artificial barriers and provide its investigators with the greatest degree of freedom, Rockefeller does not have academic departments. As a result, the university is not constrained to perform research in any particular field and can recruit the most accomplished and gifted investigators across a wide spectrum of disciplines in the sciences. Organizationally, the university’s laboratories are loosely clustered into nine distinct research areas; these research areas, some of which were pioneered at Rockefeller, represent the broad fields of study that are being pursued most actively by the university’s scientists.
