Caroline D. Nesaraja

Nuclear Physicist

Dr. Caroline D. Nesaraja is a nuclear physicist in the Physics Division at Oak Ridge National Laboratory (ORNL), specializing in the careful and detailed evaluation of nuclear structure and radioactive‑decay data. Her work focuses on the systematic assessment of nuclear level properties, electromagnetic transition properties (gamma rays), radiation‑specific decay data, and published nuclear structure and decay experimental studies. Through rigorous consistency checks, uncertainty analysis, and resolution of conflicting datasets, she produces critically evaluated “best value” results that form authoritative contributions to the Evaluated Nuclear Structure Data File (ENSDF)—the primary global standard for nuclear structure and decay information used across basic research, nuclear technology development, isotope production, astrophysics modeling, and national security applications.

Dr. Nesaraja earned her PhD in nuclear physics through a sandwich program between the National University of Malaysia and Forschungszentrum Jülich, during which she was supported as a German Academic Exchange Service (DAAD) Scholar. She serves as an Evaluator and Advisor for the IAEA’s International Network of Nuclear Structure and Decay Data Evaluators (NSDD), contributing to international evaluation guidelines and advancements in ENSDF methodologies. In 2022, she served on the NSAC Nuclear Data Subcommittee, co‑authoring recommendations that define national priorities and long‑term strategies for nuclear‑data stewardship.

Her scientific achievements have been recognized through multiple ORNL and professional honors, including UT‑Battelle awards for scientific accomplishment, the American Physical Society’s Woman Physicist of the Month recognition, and a 2024 ORNL Physics Division Certificate of Recognition. Her ongoing work advances the precision, reliability, and scientific impact of nuclear structure and decay data for the international research community.
