Postdoctoral Research Associate
Date: Mar 31, 2026
Location: Oak Ridge, TN, US, 37830
Company: Oak Ridge National Laboratory
Requisition Id 16178
Overview:
We are seeking a Postdoctoral Research Associate to support research activities within the Isotope Applications Research Group (IARG) at Oak Ridge National Laboratory (ORNL). This position will focus on the development, characterization, and application of engineered nanoparticles for medical isotope systems, including technologies relevant to isotope processing, separations, stabilization, and advanced therapeutic or diagnostic applications. The successful candidate will contribute to multidisciplinary efforts at the interface of chemistry, nanomaterials, nuclear science, and materials engineering, with emphasis on understanding material behavior in complex chemical and radiological environments. Research activities may include the design of functional nanomaterials, investigation of radiation–matter interactions, evaluation of material performance under extreme conditions, and the development of innovative approaches to improve the efficiency, selectivity, and durability of medical isotope-related processes. Opportunities will also be available to support broader programmatic efforts in materials development, radiochemical processing, and isotope application technologies.
IARG is a multidisciplinary team dedicated to advancing the production, exploration of fundamental properties, and practical applications of radioisotopes produced at ORNL. Comprised of experts ranging from nuclear engineers and radiochemists to organic chemists and cell biologists, IARG pushes the boundaries of technology in the production, isolation, and characterization of radionuclides. Their work not only enhances our understanding of these isotopes but also explores their current and potential future applications, which include innovations in nuclear battery development, cutting-edge research in next-generation nuclear reactors, and the advancement of targeted alpha therapy in cancer treatment.
Major Duties/Rsponsibilities:
- Perform experimental studies related to the design, synthesis, characterization, and application of engineered nanoparticles for medical isotope technologies.
- Develop and evaluate nanoparticle-enabled approaches for isotope stabilization, and therapeutic or diagnostic applications.
- Investigate radiation–matter interactions and the effects of chemically and radiologically challenging environments on nanomaterial performance, stability, and durability.
- Publish scientific papers and internal reports resulting from this research and present results in appropriate technical and scientific settings.
- Collaborate with a multidisciplinary team of scientists and engineers to advance isotope science through innovative materials and process development.
- Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Science.
- As a member of the ORNL scientific community, you will be expected to commit to ORNL’s Research Code of Conduct. Our full code of conduct and a statement by the Lab Director’s Office can be found here: https://www.ornl.gov/content/research-integrity
