About the Isotope Science and Engineering Directorate (ISED):
Established in 2020, the Isotope Science and Engineering Directorate is strengthening Oak Ridge National Laboratory's leadership in isotope production and enrichment technology innovation. ISED is guiding the Lab's pursuit of the fundamental science and technology that broadens the application of isotopes for energy, environmental, medical, and national security purposes. These efforts are made possible through the High Flux Isotope Reactor, the Radiochemical Engineering Development Center, ORNL's other nuclear facilities, and an assemblage of world-leading scientists and engineers.  Please visit for more information about ISED. 
This position resides in the Radioisotope Infrastructure Development (RID) Group in the Radioisotope Production Engineering and Analysis (RPEA) Section in the Radioisotope Science and Technology Division (RSTD) at ORNL. RID enables the production of a variety of important medical, scientific, and industrial radioisotopes. These include several alpha/beta emitting radioisotopes either deployed or under clinical trial for treatment of cancer (e.g., Ac-225, Ac-227, Ra-224/Pb-212, and W-188); heavy actinides Bk-249, Es-254, and Fm-257 for fundamental chemistry research and new element discovery; Cf-252 for neutron emitting applications; Pu-238 for space exploration; and Ni-63 and Pm-147 for industrial applications.
