The JSI Prize Postdoctoral Fellowship is an internationally advertised position to support an early career scientist to work on scientific topics that are the focus of the Joint Space Science Institute. Current areas of interest to JSI include strong gravity, gravitational waves, black holes, high-energy and plasma astrophysics, particle astrophysics, and cosmology. 

Beginning with the 2018-19 academic year, the fellowship has been renamed the Neil Gehrels Prize Postdoctoral Fellowship in honor of Neil Gehrels, who was key figure in the establishment of the JSI and was active in working with students and early career scientists to further their aspirations. 

Prize Postdocs are free to pursue research topics of their own choosing. They are assigned mentors appropriate for their research interests from the JSI Fellows at the University of Maryland and NASA’s Goddard Space Flight Center and typically interact with scientists both at the University and Goddard.
 
The Fellowship is for two years with a third year possible by mutual agreement.  It may be held at the same time as a NASA Hubble or Einstein Fellowship, in which case fellowship support is extended to subsequent years.  The announcement for the position normally appears in the Fall. The position includes a yearly salary and research stipend as well as benefits, including comprehensive health care.
