With this solicitation, NIJ seeks to support two (2) American Association for the Advancement of Science (AAAS) Science Technology Policy Fellowships (STPF) Fellows at NIJ. The AAAS STPF Fellow, as mutually agreed, will be assigned responsibilities across NIJs science offices depending on the interests of the science offices and the interests of the Fellows. Regardless of placement, the Fellows will have the opportunity to work across offices. The Fellows will have opportunities to engage in a range of science (including social and behavioral science), technology, engineering, and mathematics research development and evaluation projects.
